| 摘 要： | A new process named CPP (Catalytic Pyrolysis Process) for producing ethylene and propylene from heavy oil feedstock has been developed. The catalyst CEP was specially designed for this process, which has bi-functional catalytic activities for both carbonium ion reaction and free radical reaction, so as to maximize the yields of ethylene and propylene. The commercial trial showed that the yield of ethylene and propylene was 20.37% and 18.23% respectively in maximum ethylene operation with Daqing AR as feedstock, and the yield of ethylene and propylene was 9.77% and 24.60% respectively in maximum propylene operation by using the same feedstock.Compared with steam cracker, the feed cost of CPP is much lower for producing ethylene and propylene.
