▎ 摘　　要

NOVELTY - Catalyst comprises 15-20 pts. wt. kaolin, 20-25 pts. wt. pseudo-boehmite, 6-15 pts. wt. aluminum sol, 10-15 pts. wt. graphene loaded zinc oxide, 5-10 pts. wt. aluminum dihydrogen phosphate and 1-3 pts. wt. rare earth solution. USE - The catalyst is useful in half-synthesizing catalytic cracking (claimed). ADVANTAGE - The catalyst has large specific surface area, high and low nitrogen-containing quantity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing catalyst comprising crushing kaolin to grain diameter of 100-200 mu m and mixing boehmite, then adjusting pH to 3-4 using acid water to acidify, then adding aluminum sol, graphene loaded zinc oxide, aluminum dihydrogen phosphate and rare earth solution, uniformly mixing to prepare catalyst slurry, spray granulating, roasting, washing and drying to obtain catalyst.
