| 摘 要： | 建立了以乙醇、乙醛为原料，合成正丁醇的Guerbet反应数学模型。证明了模型正平衡点的存在性，分析了反应器流速、投料比对模型平衡点及其稳定性的影响，模拟了正丁醇选择性、收率与乙醇转化率随接触时间、投料比的变化状况。结果表明：在接触时间确定的情况下，可以通过调节投料比使正丁醇选择性、收率与乙醇转化率达到较高水平。

| Abstract: | A mathematical model of the Guerbet reaction for the synthesis of butanol by reaction of ethanol and acetaldehyde has been established and the existence of the positive equilibrium of the model was proved. Based on the model, we discussed the effect of varying the flow rate and feed ratio on the stability of the positive equilibrium point and simulated the changes in the selectivity, yield and conversion rate as a function of contact time and feed ratio. It was found that when the contact time is fixed, the selectivity, yield and conversion rate can be increased by adjusting the feed ratio. |
