Title:
SILICON-ALUMINUM MOLECULAR SIEVE CATALYST, AND PREPARATION AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/089338
Kind Code:
A1
Abstract:
Disclosed are a silicon-aluminum molecular sieve catalyst, and the preparation and application thereof. The desorption curve of NH3-TPD spectrum of the catalyst shows three peaks P1, P2 and P3, and the peak positions of the three peaks P1, P2 and P3 respectively correspond to desorption temperatures in the ranges of 180-220℃, 250-290℃ and 370-410℃. The catalyst has high activity, selectivity and stability when used in the gas phase alkylation reaction of an aromatic hydrocarbon and an olefin to prepare an alkyl aromatic hydrocarbon.
