optimize flue gas settings to promote microalgae growth in photobioreactors via computer simulations

从电厂烟气能促进藻类栽培和减少温室气体排放1。微藻不仅比3的植物更有效地捕获太阳能，而且合成先进的生物燃料2-4。一般情况下，大气中的CO 2是不是有足够的来源，支持最大藻类生长5。另一方面，在高浓度的CO 2的工业废气对藻类的生理不良影响。因此，无论培养条件（如营养物和光），并在烟道气流进入光生物反应器的控制是重要的，以开发一种有效的“烟道气藻类”系统。研究者提出了不同的光生物反应器配置4,6和培养战略7,8烟气。在这里，我们提出了一个协议，它演示了如何使用模型来预测响应微藻生长烟气设置。我们PERFORM两个实验说明和模型模拟，以确定烟气藻类生长的有利条件。我们开发了一个莫诺基于模型加上传质和光强度的公式来模拟在均匀光生物反应器的微藻生长。该模型模拟比较藻类生长和烟气消费在不同烟气设置。该模型说明：1）如何藻类的生长是由CO 2的不同体积传质系数的影响; 2）我们如何可以通过动态优化方法（DOA）找到最优的CO 2浓度为藻类生长; 3）我们如何设计一个矩形的通断烟气脉冲，以促进藻类生物量增长，以减少烟道气的使用量。在实验方面，我们提出了一个协议，用于不断增长的小球藻烟道气（天然气燃烧产生的）下。实验结果定性地验证了模型预测的高频烟气普LSES可以显著提高藻类栽培。

我们以前的实验分析表明，连续烟气暴露产生不利影响小球藻生长，同时降低二氧化碳曝光时间能缓解这种抑制作用13。为了更好地理解烟气流入和藻类生长的关系，我们开发的实证模型来模拟生物量生长在烟气的存在。我们假设在烟道气中含有15％的CO 2（注：从煤燃烧的典型的CO 2浓度为10-15％，而从氧燃烧电厂的烟道气具有的CO 2&gt; 15％）。的传?...
