Description

technical field [0001] The invention relates to the technical field of cracking catalysts, in particular to a petroleum hydrocarbon cracking catalyst and a preparation method thereof. Background technique [0002] Petroleum cracking (cracking) is the process of breaking hydrocarbons with relatively large molecular weight and high boiling point into hydrocarbons with relatively small molecular weight and low boiling point under certain conditions. The cracking reaction that occurs only by the action of heat is called thermal cracking, and the cracking that occurs under the action of catalysis is called catalytic cracking. [0003] Cracking is the process of petrochemical production to break the long chain hydrocarbons in petroleum fractionation products (including petroleum gas) into ethylene, propylene, etc. Processing of short-chain hydrocarbons. [0004] The use cost of the existing cracking catalyst is relatively high, and it is difficult to reuse the used materials, wh...
