摘　　要：研究碳四烯烃催化裂解制丙烯BOC-1催化剂的放大制备及其工业应用,详细介绍催化剂放大制备后实验室小试和工业应用评价结果。BOC-1催化剂在工业生产装置中运行和再生性能良好,丙烯单程收率28.5%,碳四烯烃转化率82.1%,催化剂使用周期17天,各项性能指标均超过洛阳炼化宏力化工有限责任公司的工业催化剂水平,适合进一步推广使用。建立由烯烃催化裂解、吸收稳定、气分、MTBE醚化和烷烃分离5个单元组成的碳四烯烃资源综合利用工艺流程,并使用VMGSim流程模拟软件进行模拟计算。结果表明,采用新工艺流程,碳四烯烃综合利用率99.3%,聚合级丙烯收率35.19%。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.
