Method for preparing catalytic cracking catalyst

The invention relates to a method for preparing a catalytic cracking catalyst, which comprises the following steps: (1) weighting zeolite, a binder precursor, a substrate precursor and a pulpable intermediate; (2) forming a solid-liquid slurry containing the zeolite, the binder precursor, the substrate and the pulpable intermediate; (3) stirring and/or grinding the slurry, performing a uniform mixing and uniformization to the above components to realize the refinement of particle size; (4) converting catalyst slurry into molded particles, and converting the molded catalyst particles into a catalyst finished product by drying or calcinating. The solid content in the catalyst formula is 30%-65%, the addition of the solid content enables a great addition to the apparent density of the catalyst, the addition of the catalyst bulk density enables a close association with the enhancement of the wearing performance, accordingly, the addition of the catalyst bulk density is capable of reducing the volume load of the catalyst or filling more catalyst in a given volume of a reactor.
