【Abstract】 The technology of circulation process for liquid phase alkylation of benzene with ethylene is introduced and analyzed in detail.After more than 2500?h of running on the activity-stability experiment of catalyst,the results shows that the alkylation catalyst has superior activity and stability,and the circulation process for liquid phase alkylation in fix-bed is feasible perfectly.The new process is simple and operated conveniently.Using the circulation process for liquid phase alkylation,the molar ratio of benzene to ethylene can be easily decreased,so the energy consumption of process can be reduced.更多还原
