MAC催化剂在玉门催化装置上的应用

Application of MAC catalyst in Yumen FCC unit

中石油玉门炼油厂催化装置采用两段提升管设计,装置长期存在剂耗高,催化剂自然跑损量大,烟机入口粉尘浓度高的问题,严重影响装置长周期运行。2019年5月开始应用由中石化催化剂长岭分公司采用新型粘结剂及载体技术设计的MAC专用剂,结果表明,当新剂藏量达到70%时,汽油及液化气收率提高,总液收增加,催化剂跑损量减少,油浆固含量及烟机入口浓度降低,催化剂单耗降低,有利于装置安全长周期运行。

The two-stage riser design is adopted in the FCC unit of Yumen Refinery of China National Petroleum Corporation.The unit has problems of high catalyst consumption,high catalyst loss and high dust content in inlet of gas turbin.From May 2019,the MAC special agent with new type of binder and catalyst carriers technology designed by Changling Division of Sinopec Catalyst Co.Ltd.was applied in the unit.The results showed that when the new catalyst charge reached 70%,gasoline and LPG yield was increased,the yield of valuable products was increased,catalyst running loss was reduced,solid content in slurry and the inlet concentration range hood,catalyst consumption wers reduced,which was favorable for safe and long period operation of the device.
