Laboratory Production of Biofuels and Biochemicals from a Rapeseed Oil through Catalytic Cracking Conversion

Summary

This paper presents an experimental method to produce biofuels and biochemicals from canola oil mixed with a fossil-based feed in the presence of a catalyst at mild temperatures. Gaseous, liquid, and solid products from a reaction unit are quantified and characterized. Conversion and individual product yields are calculated and reported.

Abstract

The work is based on a reported study which investigates the processability of canola oil (bio-feed) in the presence of bitumen-derived heavy gas oil (HGO) for production of transportation fuels through a fluid catalytic cracking (FCC) route. Cracking experiments are performed with a fully automated reaction unit at a fixed weight hourly space velocity (WHSV) of 8 hr^-1, 490-530 °C, and catalyst/oil ratios of 4-12 g/g. When a feed is in contact with catalyst in the fluid-bed reactor, cracking takes place generating gaseous, liquid, and solid products. The vapor produced is condensed and collected in a liquid receiver at -15 °C. The non-condensable effluent is first directed to a vessel and is sent, after homogenization, to an on-line gas chromatograph (GC) for refinery gas analysis. The coke deposited on the catalyst is determined in situ by burning the spent catalyst in air at high temperatures. Levels of CO₂ are measured quantitatively via an infrared (IR) cell, and are converted to coke yield. Liquid samples in the receivers are analyzed by GC for simulated distillation to determine the amounts in different boiling ranges, i.e., IBP-221 °C (gasoline), 221-343 °C (light cycle oil), and 343 °C+ (heavy cycle oil). Cracking of a feed containing canola oil generates water, which appears at the bottom of a liquid receiver and on its inner wall. Recovery of water on the wall is achieved through washing with methanol followed by Karl Fischer titration for water content. Basic results reported include conversion (the portion of the feed converted to gas and liquid product with a boiling point below 221 °C, coke, and water, if present) and yields of dry gas (H₂-C₂'s, CO, and CO₂), liquefied petroleum gas (C₃-C₄), gasoline, light cycle oil, heavy cycle oil, coke, and water, if present.

Introduction

There is strong global interest in both the private and public sectors to find efficient and economic means to produce transportation fuels from biomass-derived feedstocks. This interest is driven by a general concern over the substantial contribution of burning petroleum fossil fuels to greenhouse gas (GHG) emissions and its associated contribution to global warming. Also, there is strong political will in North America and Europe to displace foreign-produced petroleum with renewable domestic liquid fuels. In 2008, biofuels provided 1.8% of the world's transportation fuels¹. In many developed countries, it is required that biofuels replace from 6% to 10% of petroleum fuels in the near future². In Canada, regulations require an average renewable fuel content of 5% in gasoline starting December 15, 2010³. The Renewable Energy Directive (RED) in Europe has also mandated a 10% renewable energy target for the European Union transport sector by 2020⁴.

The challenge has been to develop and demonstrate a viable economic pathway to produce fungible transportation fuels from biomass. Biological sources include triglyceride-based biomass such as vegetable oils and animal fats, as well as waste cooking oil and cellulosic biomass such as wood chips, forest wastes, and agriculture residues. Over the past two decades, research has focused on the evaluation of biomass-derived oil processing using conventional fluid catalytic cracking (FCC)^5-12, a technology responsible for producing most of the gasoline in a petroleum refinery. Our novel approach in this study is to co-process canola oil mixed with oil sands bitumen-derived feedstock. Normally, bitumen must be upgraded prior to refining, producing refinery feedstocks such as synthetic crude oil (SCO)—this processing route is particularly energy intensive, accounting for 68-78% of the GHG emissions from the SCO production¹³ and, in 2011, constituting 2.6% of Canada's total GHG emissions¹⁴. Replacing a portion of upgraded HGO with biofeed would reduce GHG emissions, since biofuel production involves a much smaller carbon footprint. Canola oil is chosen in this work because it is abundant in Canada and the US. This feedstock possesses a density and viscosity similar to those of HGOs while the contents of sulfur, nitrogen, and metals that could affect FCC performance or product quality are negligible. Moreover, this co-processing option offers significant technological and economic advantages as it would allow utilization of the existing refinery infrastructure and, hence, would require little additional hardware or modification of the refinery. In addition, there may be potential synergy that could result in product quality improvement when co-processing a highly aromatic bitumen feed with its straight-chain biomass counterpart. However, co-processing involves important technical challenges. These include the unique physical and chemical characteristics of bio-feeds: high oxygen content, paraffinic-rich composition, compatibility with petroleum feedstocks, fouling potential, etc.

This study provides a detailed protocol for the production of biofuels at laboratory scale from canola oil through catalytic cracking. A fully automated reaction system – referred to in this work as the laboratory test unit (LTU)¹⁵ – is used for this work. Figure 1 shows schematically how this unit operates. This LTU has become the industry standard for laboratory FCC studies. The objective of this study is to test the suitability of the LTU for cracking canola oil to produce fuels and chemicals with the goal of mitigating GHG emissions.

Protocol

Caution: Please consult all relevant material safety data sheets (MSDS) before using the materials. Work with crude oil samples should only be done while wearing proper personal protective equipment (safety glasses, gloves, pants, closed-toe shoes, lab coat), and the opening, transfer and handling of crude samples should occur in a vented fumehood. Heated hydrocarbons can be flammable in air, and the reaction system should be carefully leak-checked prior to use with crude oil mixtures. The reactor can reach temperatures as high as 750 °C, and high-temperature safety gloves should be used when working near hot surfaces.

1. General Considerations

1. To make the best use of the automated reaction unit, which can complete six consecutive runs over ~8 hr, choose a constant feed rate of 1.2 g/min. This sets the weight hourly space velocity (WHSV) to 8 hr^-1 through the relationship WHSV=60/[(C/O)×t]=60×(O/t)/C where t is the feed delivery time in minutes and C and O are masses of catalyst and feed, respectively, in grams. By changing the feed injection time, a set of catalyst/oil mass ratios of 4, 6, 8, 10, and 11.25 (x2) was attained for each reaction temperature in order to achieve a wide range of conversion.

2. Feedstock and Catalyst Preparation

1. Obtain an HGO by distilling off the -343 °C fraction (by spinning band) of a synthetic crude oil (SCO).
2. Purchase edible-grade canola oil from a local food store, and use without further treatment.
3. Prepare a 15 v% canola blend by mixing 79.645 g of HGO (0.9370 g/ml density) with 13.7535 g canola oil (0.9169 g/ml density).
4. Screen the equilibrium catalyst using a 60 Tyler mesh sieve (250 µm opening), followed by a second screening with a 400 Tyler mesh sieve (38 µm opening).
5. Calcine the on-size particles (38-250 µm) at 600 °C for 4 hr, then load them into the six hoppers of the automated reaction unit.

3. Test Procedure

1. System Preparation
   1. Program Preparation
      1. Using the software that controls the reaction unit, open the window for run conditions.
      2. Type in the identifications of the feed and catalyst, the barometric pressure, the injection time, and the temperature set points for the feed system, the reactor, the product line, the coolant, and the CO catalytic converter in each step of the run period.
   2. Catalyst Preparation
      1. For each catalyst glass hopper above the process tubing, remove the lid and charge 9 g of calcined on-size catalyst into the hopper. Attach an O-ring to the top of the hopper and re-clamp its lid.
   3. Calibration of Feed Rate
      1. Set the oil feed pump to deliver feed at a constant feed injection rate (1.2 g/min) for all the cracking runs.
      2. Disconnect the oil feed line below the purge valve (KV-114)¹⁶ and attach a short temporary tube to the bottom of the valve for oil delivery into a tared beaker.
      3. Preheat the feedstock to 85 °C to enable the HGO-blend to flow easily in and out of the syringe and along the feed line.
      4. Set the injection time for calibrating the pump to the same value as that for the first run in the series (default setting).
      5. Tare a beaker, and place it at the discharge of the short temporary tubing. Start the preset "PUMPCAL" user program¹⁷ in the reaction unit software.
      6. After the PUMPCAL program is complete, remove and weigh the beaker containing the feed. Divide the mass of feed delivered into the beaker by the injection time to obtain the feed rate.
      7. Adjust the pump speed to higher or lower (using the three-digit dial on the pump) and repeat steps 3.1.3.5 to 3.1.3.6 until the desired feed rate is attained.
      8. Remove the short temporary tube and re-connect the feed line.
   4. Calibration of GC for Gas Analysis
      Note: This step is necessary if the GC for gas analysis is found to be out of calibration, which can be inferred from reference checks, data trending, and material balance. Experience indicates that the GC calibration can be relied on for an extended period.
      1. Connect a cylinder of commercial multicomponent refinery gas standard to the hand valve (HV-190)¹⁶.
      2. Load a method in the GC software that is capable of eluting and separating all the peaks in the refinery gas standard. Use the parameters for the GC method in Table 1.
      3. Using the GC software, perform an analysis run of the refinery gas standard.
      4. Open the chromatogram of the refinery gas standard and integrate the peaks in the chromatogram.
      5. Identify the peaks in the chromatogram, ensuring that all of the components in the calibration gas are found. Delete any peaks that are present but cannot be attributed to the components in the standard.
      6. Based on retention time ranges, lump and divide compounds eluting after C₅ into C₆₊₁, C₆₊₂, C₆₊₃, and C₆₊₄ groups. For this method, lump pentene isomers into one C₅ olefin group.
      7. Using the GC software, assign concentration values to each integrated peak from the gas standard, under the Calibration function.
      8. Save the calibration into the method file, for use to determine the concentrations of peaks in subsequent test runs. Disconnect the commercial gas standard.
   5. Calibration of CO₂ Analyzer
      1. Through the reaction unit software, switch the valve (KV-170)¹⁶ to the position that enables the zero gas (nitrogen) to flow to the IR gas analyzer. Adjust the flow by turning the knob in association with the flow control valve (FCV-107)¹⁶, if necessary, to get about 250 sccm on the flow indicator (FI-107)¹⁶.
      2. Zero the analyzer using the Zero adjustment screw on the front panel of the analyzer with the help of a flat-bladed screwdriver.
      3. Switch the hand valve (HV-107)¹⁶ to supply the CO₂ (19.8 mole%) standard gas to the analyzer. Adjust the manual valve (MV-107)¹⁶ to obtain a flow of approximately 250 sccm on the flow indicator (FI-107).
      4. Adjust the analyzer reading to match the concentration (19.8 mole%) of the standard span gas using the SPAN screw on the front panel.
      5. Disconnect the span gas and return the hand valve (HV-107) to the RUN position.
   6. Preparation of Liquid Product Receiver
      Note: Each receiver consists of a condenser and a GC vial connected to the bottom of the condenser by a short piece of silicone tubing.
      1. Sequentially assign numbers to the condensers and GC vials.
      2. Place a small plug of glass wool inside the top of each receiver outlet arm as shown in Figure 2.
      3. Keep the receiver upright with some support in a beaker or a flask of suitable size. Weigh each receiver in an analytical balance the top window of which is covered by a cubic plastic shield to ensure a draft-free environment (Figure 3).
      4. Record the dry mass (W_before) of the prepared receiver together with labeled stoppers.
      5. Install and connect the weighed receiver to the product line (Figure 4).
   7. Reactor Preparation
      1. Install an oil feed line in the reactor with a length that allows for a 1.125 inch injector height.
      2. Place a filter at the exit of the reactor to prevent any catalyst dust from entering the product line, changing the filter after 50-100 runs.
      3. Perform a pressure test on the reactor system by running the program PTEST1¹⁷ after feed pump calibration and installation of the receivers. Close the gas vent and pressurize the reactor system with 150 mmHg nitrogen, followed by isolation of the system.
      4. Observe the pressure reading for a few minutes to ensure the pressure drop is no more than 0.4 mmHg per min indicating that no leaks are present. If a pressure drop of greater than 0.4 mmHg per min is observed, perform a leak test according to the manufacturer's instructions, and remedy any leaks accordingly.

2. System Operation in Auto Mode
   1. On the LTU SETUP screen, input the relevant information for the experiment: run number, feed name, catalyst identification, atmospheric pressure, set points for skin and internal reactor temperatures for both cracking and catalyst regeneration, and oil injection time. Omit this step if full information has been included in Section 3.1.1.
   2. Place the system into run mode by clicking the "RUN" button on the process flow screen. This initiates the test sequence¹⁷, which includes the steps in auto mode to be described in the Discussion.
3. Non-Auto Mode System Operation
   1. Using the computer attached to the GC, integrate the peaks and process the data using the calibration established. Input the final GC data into the LTU program through the LTU computer.
4. Post-run Operation
   1. Mass Determination of Liquid Product
      1. After removing the clamp, tilt the receiver and collect any liquid product droplets on the beveled metal tip below the product valve.
      2. Immediately seal the receiver with labeled rubber stoppers and carefully remove it from the bath. Rinse off the ethylene glycol from the bath with cold water and dry the outside with paper towel.
      3. Place the liquid product receiver on a rack at room temperature for 20 min, allowing any frozen product to thaw and run down into the GC vial at the bottom of the receiver.
      4. Collect the liquid holdup around the metal joint for the receiver with a tared cotton wool swab. Determine the mass of the liquid holdup (W_swab) and record.
      5. Open the liquid product receiver to atmosphere in a vented fume hood for pressure equalization by momentarily removing the stopper on the top outlet of the receiver.
      6. Put the stopper back on and obtain the receiver mass (W_after). Remove the GC vial from the condenser. Cap and store the product sample in a refrigerator at 4 °C for later analysis.
      7. If a water droplet appears at the GC vial bottom as in the case of cracking canola oil, use a clean syringe to transfer as much water-free oil product to another vial as possible and cap it immediately.
      8. Rinse the inner walls of the receiver condenser thoroughly with a small quality of methanol and collect all of the methanol wash into the original GC vial containing the water droplet. Cap the vial and obtain the mass of the liquid inside for use in water determination.
   2. Analysis of Liquid Product for Simulated Distillation
      1. Using standard test method ASTM D2887¹⁸, determine the mass percentage of the water-free liquid product boiling in the ranges of gasoline (IBP-221 °C), light cycle oil (LCO, 221-343 °C), and heavy cycle oil (HCO, 343 °C-FBP).

   4. Mass Balance (Recovery)
      1. Calculate the mass balance using
          
         R = (W_gas + W_liq + W_coke) ÷ W_feed × 100
          
         where R is recovery (mass% of feed) and W_feed is mass (g) of the oil feed. R should be in the range of 96 to 102%. If not, reject the test as unsatisfactory.

Results

The established protocol has been successfully applied to an oil blend of 15:85 volume ratio (i.e., 14.73:85.27 mass ratio) between canola oil and an SCO-derived HGO²⁰. For practical reasons (cost, availability of canola oil, and possible challenges in commercial operation), the study was focused on feedstock containing 15 v% canola oil addition, although feeds with higher concentrations were also tried. The blend was catalytically cracked at 490-530 °C and 8.0 hr...

The oil to be cracked is preheated and fed from the top through an injector tube with its tip close to the bottom of the fluid bed. The vapor generated after catalytic cracking is condensed and collected in a receiver, and the liquid product collected is subsequently analyzed for simulated distillation to determine yields of fractions in diff...
