Suspension catalytic distillation of simultaneous alkylation and transalkylation for producing cumene

摘要

This work deals with the improvement of the suspension catalytic distillation (SCD)process.An improved process that alkylation and transalkylation reactions for producting cumene are carried out simulataneously i a scd column,was put forward.The inetic data of alkylation of benzene with proplyene oer a modified beta-zeolite catalyst,YSBH-01,were determined in a fixed-bed laboratory micro-reactor.On this basis,the equilirium stage (EQ)model (MESHR equatins)is established to simulate the SCD column.The performance of The SCD column is discussed.The innovation present in this work for the SCD process is also suitable for the fixed-bed catalytic distillation (FCD)process for producing cumene.
