Simulation on Residence Time Distribution of Light Phase Liquids in an Ionic Liquid Catalyzed iso-Butane Alkylation Cyclone Reactor
摘要
Abstract
A liquid-liquid cyclone reactor was proposed for iso-butane alkylation catalyzed by ionic liquids. The reaction and separation were happened simultaneously in the reactor. RSM model combined with Eulerian multiphase and Transport models were used to simulate residence time distribution (RTD) of light-phase liquids in the reactor. The effects of flow rate ratio of heavy/light phases and total inlet flow rates on RTD were also investigated. The results show that the experimental values of mean residence time (MRT) are closed to the simulated values. The RTD curves show one single peak without a long tail, which indicates that there is no obvious back-mixing in the liquid-liquid cyclone reactor. MRT decreases as the inlet flow increases. Finally, the relationship between the mean residence time and the inlet flow are established, and proper operation conditions can be predicted base on the reaction time of iso-butane alkylation.关键词
