摘　　要：为了进一步提高丙烯产率,石油化工科学研究院开发了催化裂解催化剂MMC-1。该催化剂在沈阳石蜡有限公司催化裂解装置上进行了工业应用。标定结果表明,采用DCC-Ⅱ操作条件,使用MMC-1催化剂以后,液化气中的丙烯体积分数由47.15%增加到52.12%,丙烯产率由12.41%增加到14.57%;稳定汽油中烯烃体积分数降低了7.0个百分点。同时芳烃体积分数由13.0%增加到16.7%,汽油的其它性质变化不大,汽油总体质量变好。In order to further increase the yield of propylene, a DCC catalyst MMC-1 was developed. The first commercial trial of MMC-1 was carried out in a DCC unit at Shenyang Wax Chemical Company. The test run results showed that after the application of MMC-1 catalyst under the operating conditions of DCC- Ⅱ , the propylene in LPG increased from 47.15 v% to 52.12 v% ; the propylene yield increased from 12.41% to 14.57%; and the olefin content in naphtha reduced by 7. 0 percentage points together with an aromatics content increased from 13.0% to 16.7%.
