Catalyst for propylene production from C4 alkenes and its industrial application

The scale-up preparation and industrial application of BOC-1 catalyst for catalytic cracking of C₄ alkenes to propylene were investigated,and the results of laboratory test and industrial application evaluation of the catalyst prepared by enlarged scale-up were introduced in detail.The BOC-1 catalyst had good performance in operation and regeneration in the industrial plant.The single-pass yield of propylene was 28.5%,the conversion of C₄ alkenes was 82.1%,and the regeneration period of the catalyst was 17 days.The catalytic performance of BOC-1 catalyst was much better than the existing industrial catalyst in Luoyang Refinery Hongli Grace Chemical Co.,Ltd,,and the BOC-1 catalyst is suitable for further promotion and commercial application.A novel process flow for integrated utilization of C₄ alkenes resources consisting of olefin catalytic cracking unit,absorbing-stabilizing unit,gas separation unit,MTBE etherification unit and alkane separation unit was established and simulated by VMGSim process simulation software.It was showed that,the integrated utilization efficiency of C₄ alkenes and the yield of polypropylene could reach 99.3% and 35.19%,respectively,in the new process.
