摘　　要：中国石化石油化工科学研究院开发的新一代高丙烯、低生焦的催化裂解专用催化剂DMMC-3在中海石油宁波大榭石化有限公司催化裂解装置上进行了工业应用。标定结果表明,在催化裂解原料性质和操作工况基本相当的情况下,与上一代DMMC-2催化剂相比,在DMMC-3催化剂作用下丙烯收率增加0.56百分点,液化气中的丙烯体积分数增加1.74百分点,焦炭产率下降0.1百分点,此外也提高了干气中乙烯浓度。这说明DMMC-3催化剂能够提高丙烯的收率和选择性,同时降低生焦,提升装置的经济效益。The commercial application of DMMC-3,a new special catalyst for catalytic cracking with characteristics of high propylene and low coke,developed by SINOPEC Research Institute of Petroleum Processing,has been carried out in the catalytic cracking unit of CNOOC Ningbo Daxie Petrochemical Co.The calibration results showed that the propylene yield and propylene concentration in LPG were increased by 0.56 and 1.74 percentage points,respectively.Compared with the previous generation of DMMC-2 catalyst,coke was decreased by 0.1 percentage point,in addition to increasing the concentration of ethylene in dry gas.The DMMC-3 catalyst could improve the yield and selectivity of propylene,reduce coke formation and increase the economic benefit of the unit.
