Title:

DISPROPORTIONATION AND TRANSALKYLATION CATALYST, AND PREPARATION AND APPLICATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2022/063266

Kind Code:

A1

Abstract:

Disclosed are a disproportionation and transalkylation catalyst and the preparation and application thereof, the catalyst comprising an acidic molecular sieve and a first metal component and an oxide adjuvant loaded on the acidic molecular sieve, a first metal in the first metal component being selected from at least one of group VB metals, group VIB metals, and group VIIB metals, the amount of medium-strong acid of the catalyst being a 0.05-2.0 mmol/g catalyst, and the proportion of medium-strong acid in the total acid amount being 60-99%. When used for the catalytic conversion of alkyl aromatic hydrocarbons, the catalyst has the advantages of high reaction activity and low aromatic hydrocarbon loss.
