Abstract A catalytic thermocracking process of heavy petroleum hydrocarbon for higher output of ethylene and propylene includes preheating heavy petroleum hydrocarbon, and catalytic thermoracking reaction of said heavy petroleum hydrocarbon with catalyst containing ZSM-5 molecular sieve at 650-750 deg.C and 0.15-0.4 MPa for 0.2-5 seconds under the existance of high-temp steam. The wt. ratio of raw oil, catalyst and steam is 1:(15-40):(0.3-1). It features that said ZSM-5 molecular sieve contains AG or Cu.
