Abstract

The present invention relates to a composite start-up catalyst, characterized in that, based on the dry basis weight of the composite start-up catalyst, the composite start-up catalyst comprises 15-95 wt% of Component A catalyst, which is selected from a deep catalytic cracking or catalytic cracking equilibrium catalyst and/or a deep catalytic cracking or catalytic cracking equilibrium catalyst after treatment, wherein the treatment includes demetallization treatment and/or particle diameter adjustment treatment, and 5-85 wt% of Component B catalyst, which is selected from one or more fresh deep catalytic cracking catalyst or catalytic cracking catalyst, and optionally Component C catalyst; said Component C catalyst contains 2-10 wt% of an oxide of a modifying metal. The present invention also relates to a method for preparing the above composite start-up catalyst, its use in the start-up of a deep catalytic cracking or catalytic cracking unit, and a start-up method for a deep catalytic cracking or catalytic cracking unit.
