摘要
本文介绍了国产ZCM－7超稳Y型分子筛渣油裂化催化剂在100×10^4t/a重油催化裂化装置上的应用试验结果。标定数据和生产统计数据表明，在原粒油中减压渣油掺炼比为20－23m％时，采用ZCM－7催化剂所得汽油产率可达50m%以上，汽油辛烷烷值MON和RON分别为80和93以上，与进口Octacat-D催化剂相当，ZCM－7剂的气体和焦炭选择性也与Octacat-D催化剂接近。ZCM－7催化剂可以代替进口催化剂在重油催化裂化装置上使用。
The performance of domestic ultra-stable zeolite catalyst ZCM-7 for heavy oil cracking was tasted in a 100×10~4t/a FCCU.The results indicate that,with a feedstock containing 20～23m% of vacuum residue,ZCM-7 gives a gasoline yield of 50m%.The RON and MON of the gasoline are 93 and 80,respectively.These results are equivalent to those of Octacat-D.The gas and coke selectivities of ZCM-7 are also close to those of Octacat-D.It is concluded that the ZCM-7 can be used as an alternative of imported catalyst for heavy oil cracking.
