Abstract
A heavy fraction oil is catalytically cracked by contacting the oil with a catalyst mixture consisting of 60 to 95 wt % of a base cracking catalyst containing an ultra stable Y-type zeolite and less than 0.5 wt % of rare-earth metal oxide, and 5 to 40 wt % of an additive containing a shape-selective zeolite, in a fluid catalytic cracking apparatus under conditions that a reaction zone outlet temperature is in the range of 580 to 630.degree. C., the catalyst/oil ratio is in the range of 15 to 40 wt/wt, and the contact time of hydrocarbons in the reaction zone is in the range of 0.1 to 1.0 seconds, wherein the yield of light-fraction olefins can be enhanced.
