METHOD FOR PRODUCING CATALYST FOR CATALYTIC CRACKING OF HYDROCARBON, METHOD FOR PRODUCING AROMATIC HYDROCARBON AND/OR OLEFIN HAVING FOUR OR LESS CARBON ATOM, AND CATALYST FOR CATALYTIC CRACKING OF HYDROCARBON

摘要

PROBLEM TO BE SOLVED: To provide a technique for improving steam resistance of a catalyst for catalytic cracking of hydrocarbons to increase the yields of an aromatic hydrocarbon and/or olefin having ≤4 carbon atoms.

SOLUTION: The method for producing the catalyst for catalytic cracking of hydrocarbons comprises: a step (1) of mixing zeolite, a water-soluble aluminum-containing compound and water to obtain a catalyst precursor obtained by supporting aluminum on the zeolite; and a step (2) of mixing the catalyst precursor, a water-soluble phosphorus-containing compound and water to obtain the catalyst for catalytic cracking of hydrocarbons obtained by supporting phosphorus on the catalyst precursor.
