中文摘要：
采用建立数学模型的方法在鼓泡浆态床反应器体系中讨论了气体添加对费托合成反应行为的影响。先采用惰性气体添加的方法找到最适合鼓泡塔反应器体系的气体添加模拟方法,在最优方法中,随气体添加相应改变总压和扩散高度以保持合成气分压和空速不变。采用该方法讨论了二氧化碳和烯烃对反应行为的影响。结果表明,随二氧化碳添加量的增加,合成气转化率降低,二氧化碳的添加使得总烯烷摩尔比增加,二氧化碳添加主要通过水煤气变换反应影响费托合成行为;烯烃添加将抑制小于其碳数的烃类的生成,促进大于其碳数的烃类的生成。
英文摘要：
The effects of co-feeding gas on Fischer-Tropsch synthesis were studied in slurry bubble column reactor by modeling simulation.The optimized method of co-feeding gas in slurry bubble column was firstly selected through co-feeding inert gas.In this method,total reaction pressure and dispersion height were changed with co-feeding gas to keep the partial pressure of syngas and space velocity unchanged.Based on this method,the effects of CO2 and lower carbon olefins on Fischer-Tropsch synthesis were simulated.The results show that with inlet CO2 increasing the conversion of syngas decreases.The increasing CO2 results in the increasing of the mole ratio of olefin to paraffin;CO2 mainly affects the reactions of Fischer-Tropsch synthesis from water/gas shift reaction;when olefins are co-fed,the formation rates of hydrocarbons lighter than co-feeding olefin are suppressed,while the formations of hydrocarbons heavier than co-feeding olefin are enhanced.
