Catalyst for catalytic cracking of mixed raw material of diesel and methanol and preparation method therefor

Abstract

The present invention relates to a catalyst and a preparation method therefor, wherein the catalyst can convert diesel, which is increasingly likely to be unused, to a basic chemical raw material, and induce a thermal polymerization reaction by combining a strong endothermic reaction of diesel with an olefin reaction of methanol, which is a type of exothermic reaction, to minimize the amount of energy used in a catalytic cracking reaction of diesel. An aspect of the present invention provides a catalyst for use in a reaction for preparing a hard olefin by catalytic cracking of a mixture of diesel and methanol, and is technically characterized in that the catalyst comprises: porous zeolite with pores; and phosphorus supported inside the pores of the porous zeolite and/or on the surface of the porous zeolite, and the catalyst has a retention time of isobutane gas in the pores of 0.400-1.240 min/g.
