Protokollen er beskrevet her utnytter syklisk drift av en enkelt reaktor inneholdende en gruppe med fluidiserte katalysatorpartikler for å simulere mate olje krakking og katalysatorregenerering. Oljen som skal krakkes forvarmes og mates fra toppen gjennom en injektor rør med sin spiss nær bunnen av hvirvelsjiktet. Dampen som genereres etter katalytisk krakking blir kondensert og samlet i en mottaker, og det flytende produkt oppsamlet blir deretter analysert for simulert destillasjon for å bestemme utbytter av fraksj...

Det er sterk global interesse i både privat og offentlig sektor for å finne effektive og økonomiske midler til å produsere transport drivstoff fra biomassebasert råstoff. Denne interessen er drevet av en generell bekymring over betydelig bidrag av brennende olje fossilt brensel til drivhusgasser (GHG) og tilhørende bidrag til global oppvarming. Også er det sterk politisk vilje i Nord-Amerika og Europa for å fortrenge utenlandske produsert petroleum med fornybare innenlandske flytende brensel. I 2008 biodrivstoff forutsatt 1,8% av verdens transport brensel 1. I mange utviklede land, er det nødvendig at biodrivstoff erstatter fra 6% til 10% av fyringsoljer i nær fremtid to. I Canada, forskrifter krever et gjennomsnittlig fornybart drivstoff innhold på 5% i bensin starter 15 desember 2010 3. Fornybardirektivet (RED) i Europa har også mandat til en 10% fornybar energi målet for EU transport sektor innen 2020 4. Utfordringen har vært å utvikle og demonstrere en levedyktig økonomisk vei til å produsere ombyttelige transport drivstoff fra biomasse. Biologiske kilder inkluderer triglyserid-baserte biomasse som vegetabilske oljer og animalsk fett, samt avfall matolje og cellulose biomasse som flis, skogsavfall og landbruk rester. I løpet av de siste to tiårene har forskningen fokusert på evaluering av biomasse-avledet olje behandling ved hjelp av konvensjonelle fluid katalytisk cracking (FCC) 5-12, teknisk ansvarlig for å produsere det meste av bensin i en oljeraffineri. Vår ny tilnærming i denne studien er å co-prosessen rapsolje blandet med oljesand bitumen-avledet råstoff. Normalt må bitumen bli oppgradert før raffinering, produsere raffineriråstoffer som syntetisk råolje (SCO) -dette behandling ruten er spesielt energikrevende, og står for 68-78% av GHG emissions fra SCO produksjon 13, og i 2011, noe som utgjør 2,6% av Canadas totale klimagassutslipp 14. Å erstatte en del av oppgradert HGO med biofeed vil redusere klimagassutslippene, siden produksjon av biodrivstoff innebærer en mye mindre karbonfotavtrykk. Rapsolje er valgt i dette arbeidet fordi det er rikelig i Canada og USA. Dette råmaterialet besitter en densitet og viskositet lik de HGOs mens innholdet av svovel, nitrogen og metaller som kan påvirke ytelsen FCC eller produktkvalitet er ubetydelig. Videre vil dette ko-prosessering alternativet gir betydelige teknologiske og økonomiske fordeler som det ville tillate utnyttelse av det eksisterende raffineri infrastruktur og dermed ville kreve lite ekstra maskinvare eller modifisering av raffineriet. I tillegg kan det være potensial synergi som kan føre til bedre produktkvalitet ved samtidig behandling en svært aromatiske bitumen mate med sin rettkjedet biomasse motstykke. Men co-behandlinginnebærer viktige tekniske utfordringer. Disse inkluderer de unike fysiske og kjemiske egenskapene til bio-feeds: høyt oksygeninnhold, parafinrike komposisjon, kompatibilitet med petroleumsråstoffer, begroing potensielle, etc. Denne undersøkelsen gir en detaljert protokoll for produksjon av biodrivstoff i laboratorieskala fra rapsolje ved katalytisk krakking. En helautomatisk reaksjonssystem - som er nevnt i dette arbeidet som laboratorietestenhet (LTU) 15 - brukes til dette arbeidet Figur 1 viser skjematisk hvordan dette skal fungere.. Dette LTU har blitt en industristandard for laboratorium FCC studier. Målet med denne studien er å teste egnetheten av LTU for sprengning rapsolje til å produsere drivstoff og kjemikalier med mål om å dempe utslippene av klimagasser. <img alt="Figur 1" src="/files/ftp_upload/54390/54390fig1.jpg" /> Figur 1: Konseptuell illustration av reaktoren.

laboratory production of biofuels and biochemicals from a rapeseed oil through catalytic cracking conversion

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 &#176;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 &#176;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 &#176;C (gasoline), 221-343 &#176;C (light cycle oil), and 343 &#176;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 &#176;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.

Den etablerte protokollen har blitt brukt til en oljeblanding av 15:85 volumforhold (dvs. 14,73: 85,27 masseforhold) mellom rapsolje og en SCO-avledet HGO 20. Av praktiske grunner (kostnader, tilgjengelighet av rapsolje, og mulige utfordringer i kommersiell drift), ble studien fokusert på råmateriale inneholdende 15 vol% rapsolje tillegg, selv om strømmer med høyere konsentrasjoner ble også prøvd. Blandingen ble katalytisk krakket ved 490-530 ° C og 8,0 time <s...

Laboratory produksjon av biodrivstoff og biokjemikalier fra en rapsolje gjennom Catalytic Cracking Conversion

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 ...

The overall goal of this laboratory method is to produce biofuels and biochemicals from co-processing of canola oil with fossil-based feeds. This method can help answer key questions in chemical engineering, really, into catalytic cracking of heavy oils, fuel chemistry, catalysis, and reaction mechanisms. The main advantage of this technique is that the method is fast and cost effective, enabling full control over the test parameters and the reduction of human error.The implications of this technique extend towards catalyst development, as the equipment used is simple, reliable, and productive for testing new formulas. Although this study focus on product distribution and the quality, the main study can also be applied to other fields such as predictive modelling and simulations. I'm pleased to introduce my teammates.Research Scientist, Nicole Heshka, Yi Zhang, and R&D program advisor Edward Little. They will demonstrate the procedure and/or discuss the method. To begin this procedure, disconnect the oil feed line below the purge valve of a laboratory test unit, or LTU, and attach a short temporary tube to the bottom of the valve.Following this, preheat a previously prepared feedstock to 85 degrees celsius to enable the heavy gas oil, or HGO, blend to flow easily. Place a tared beaker at the discharge of the short temporary tube connected to the oil feed pump. Then start the preset pump cal user program in the reaction unit software.After the pump cal program is complete, remove and weigh the beaker containing the feed. Divide the mass of the feed delivered into the beaker by the injection time. Next, adjust the pump speed using the three digit dial on the pump, and repeat the previous steps until the desired feed rate of 1.2 grams per minute is attained.Then remove the short temporary tube and reconnect the feed line. Through the reaction unit software, switch the valve to the position that enables the zero gas to flow to the IR analyzer. Turn the knob in association with the flow control valve to get about 250 standard cubic centimeters per minute on the flow indicator.Following this, zero the analyzer using the zero adjustment screw on the front panel with a flat-bladed screw driver. Switch the hand valve to supply the carbon dioxide standard gas to the analyzer. Then adjust the manual valve to obtain a flow of approximately 250 standard cubic centimeters per minute.Adjust the analyzer reading to match the concentration of the standard span gas using the span screw on the front panel. Place a small plug of glass wool inside the top of each receiver outlet arm. Following this, place the receiver in a flask of suitable size to keep it upright.Then weigh the receiver in an analytical balance covered by a cubic plastic shield to ensure a draft-free environment. Now install and connect the weighed receiver to the product line. Install an oil feed line in the reactor with a length that allows for 1.125 inch injector height.Place a filter at the exit of the reactor to prevent any catalyst dust from entering the product line, changing the filter after 50 to 100 runs. It is critical to maintain consistency between runs. For example, always use an on size and coke-free equilibrium catalyst, oil feed line in the reactor with the same injector height, and constant molecular weight for the C5 plus unresolved gas lump.After feed pump calibration and receiver installation, perform a pressure test on the reactor system by running the program PTEST1. Close the gas vent and pressurize the reactor system with 150 millimeters mercury of nitrogen followed by isolation of the system. Observe the pressure reading for a few minutes to ensure the pressure drop is no more than 0.4 millimeters of mercury per minute, indicating that no leaks are present.On the LTU setup screen, input the relevant information for the experiment. Then place the system into run mode by clicking the Run button on the process flow screen. Observe as fresh catalyst from the specified hopper is discharged into the reactor.At this point, monitor the reaction system to ensure it reaches the correct conditions previously specified in the software. When the reaction conditions are met, watch to see that the syringe pump delivers the oil feed into the reactor. Following feed injection, observe vapor products flowing through the liquid receivers into the water displacement system for gas collection.Check to see that the high boiling products are condensing in the liquid receivers. At the end of the catalyst's stripping cycle, watch to ensure that the air flow begins and the reactor temperature is raised to approximately 715 degrees celsius. Monitor the IR analyzer which should show a sharp increase in carbon dioxide concentration followed by a decrease to below 0.3%At the end of the catalyst regeneration, ensure that the computer software records the mass of displaced water along with the pressure and temperature of the gas in the collection vessel.After mixing and warming to approximately 30 degrees celsius, observe delivery of the gas to the GC for analysis. Observe the reactor cooling down to skin temperatures, 50 degrees celsius below the reaction set points. Save all the data for the run.If it is the last run, discharge the spent catalyst to the waste vessel. Using the computer, attach to a gas chromatograph, or 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.For good material balance, it is critical to accurately determine the mass of liquid product, including water if present. The following steps include the methodology to recover the liquid product, in a way the long liquid product receiver, in a draft-free environment. After removing the clamp from the liquid product receiver, tilt the receiver and collect any liquid product droplets on the beveled metal tip below the product valve.Immediately seal the receiver with labeled rubber stoppers and carefully remove it from the ethylene glycol bath. Rinse off the ethylene glycol with cold water, and dry the receiver with a paper towel. Following this, place the liquid product receiver on a rack at room temperature for 20 minutes, allowing any frozen product to thaw and run down into a GC vial placed at the bottom of the receiver.Collect the liquid holdup around the metal joint of the receiver with a teared cotton wool swab. Determine the mass of the liquid holdup. Open the liquid product receiver to atmosphere in a vented fume hood for pressure equalization by momentarily removing the stopper from the top outlet.After replacing the stopper, obtain the receiver mass. Next, remove the GC vial with the sample from the condenser. Close and store the vial in a refrigerator at four degrees celsius for later analysis.If a water droplet is observed in the bottom of the GC vial, use a clean syringe to transfer as much water-free oil product as possible to another vial and close it immediately. Rinse the inner walls of the receiver condenser thoroughly with a small quantity of methanol, and collect all of the methanol wash into the original GC vial containing the water droplet. Finally, close the vial and obtain the mass of the liquid for water analysis.The yield and conversion data show qualitatively that upon cracking, canola oil in the HGO blend contributes substantially to the yields of biofuels and biochemicals. The presence of water and carbon monoxide plus carbon dioxide as cracked products from the blend but not from HGO alone, indicates that canola oil participates in reactions. The hydrogen and carbon monoxide yields are not very sensitive to catalyst to oil ratio changes for a feed at a given temperature.However, for a feed at a given catalyst to oil ratio, both hydrogen and carbon monoxide yields increase with increasing temperature, which is the driving force for cracking. Comparing the two feeds, the blend gives higher carbon monoxide yields but lower hydrogen yields than the base oil. After injection of an oil, the reactor temperature drops, reaching a minimum and then rising towards the initial temperature of 530 degrees celsius.As the catalyst to oil ratio increases, the temperature drop decreases since less oil is injected. Comparing the two feeds, the blend consistently exhibits a smaller drop of temperature due to heat release from the exothermic reaction. While attempting this procedure, it is important to carefully follow the instructions accompanying the laboratory test unit, and to maintain consistent operation between tests.Demonstration of this procedure is useful because the steps for recovery of liquid product are critical to test quality but are difficult to describe in writing. Following this procedure, other feeds like light tight oil can be co-processed with heavy crudes in order to answer questions about their suitability for refinery operations. Don't forget that crude oil can be hazardous and should only be handled while wearing proper protective equipment.Additionally, toxic hydrogen sulfide may be present in products and exhaust gas. They should only be handled under good ventilation. After watching this video, you should have a good understanding of how to operate a laboratory test unit for quality results and how to properly collect products for further analysis.
