Description

technical field

[0001] The present invention relates to a petroleum hydrocarbon cracking catalyst and a preparation method thereof, and more particularly relates to a silicon-aluminum matrix petroleum hydrocarbon cracking catalyst and a preparation method thereof. Background technique

[0002] Since the 1980s, catalytic cracking has developed from wax oil cracking to residual oil cracking, and the amount of slag added has increased year by year. Since the residual oil contains macromolecular compounds such as colloidal asphaltenes, it cannot enter the molecular sieve channels of the catalyst for cracking reactions. Seriously affect the reaction performance of the catalyst.

[0003] In recent years, with the increasingly stringent environmental protection requirements, gasoline standards have also undergone major adjustments, and the olefin content in gasoline is used as the quality index of gasoline. In 1999, China's State Environmental Protection...
