摘　　要：介绍中国石化股份有限公司北海分公司在重油催化裂化装置上进行的MGD技术工业试验和生产低烯烃汽油的情况。生产结果表明 :采用RGD C催化剂、MGD技术和操作条件优化相结合 ,诸如汽油回炼 ,保持较高平衡催化剂活性及降低反应温度等 ,可以使常压渣油为原料的重油催化裂化汽油烯烃体积分数从 5 4 .3%降至 2 8.0 % ,RON变化不大 ,MON明显上升 ,抗爆指数增加。液化气产率提高 3.98个百分点 ,柴油产率提高 0 .4 3个百分点 ,汽油产率降低 2 .15个百分点 ,油浆产率降低 3.0 2个百分点。The commercial trial and production of low olefin content naphtha with MGD technology in the heavy oil FCCU of SINOPEC Baihai Company were introduced. The production result showed that processing atmospheric residue over RGD-C catalyst and combined the MGD technology with optimizing operation conditions, such as naphtha recycle, keeping higher equilibrium catalyst activity and lowering the reaction temperature, etc., could reduce the cracked naphtha olefin content from 54.3 v% to 28.0 v%. The naphtha RON only slightly changed, however, the MON and antiknock index enhanced obviously. The LPG and LCO yields increased by 3.98 and 0.43 percentages respectively, and the naphtha and slurry yields decreased by 2.15 and 3.02 percentages respectively.
