Intensification and Optimization of Fluidized Bed Reactor for Production of Liquid Fuels for the Next Generation

合成气生产液体燃料伴随着气体体积的减小。当涉及气体体积减少的反应在流化的催化剂床上进行时，发生脱流化。改善流化质量的一种方法是用反应物气体供应惰性气体：过量供应其中一种反应物也可获得类似的效果。本研究通过在流化催化剂床上进行CO2加氢，定量分析了稀释后的反应物气体对流化质量的影响。通过运行流化床，避免脱流区存在的影响流化质量的两个参数，可以建立稳定的运行。

Liquid fuel production from synthesis gas is accompanied with a decrease in gas volume. Defluidization occurs when the reaction involving a decrease in gas volume are carried out in a fluidized catalyst bed. One method to improve fluidization quality is to supply an inert gas with reactant gases : similar effect can be obtained by supplying an excessive amount of one of the reactants. In the present study, the effect of a diluted reactant gas on fluidization quality is quantitatively analyzed by performing CO2 hydrogenation in a fluidized catalyst bed. Stable operation can be established by operating the fluidized bed to avoid the conditions contained in the defluidization zone using two parameters that influence fluidization quality.
