Estimating the term…
A disproportionation and transalkylation catalyst can be used in the catalytic conversion of alkyl aromatic hydrocarbons. The catalyst contains an acidic molecular sieve, a first metal component immobilized on the acidic molecular sieve and an oxide additive. The first metal contained in the first metal component is at least one selected from the group of Group VB metals, Group VIB metals and Group VIIB metals, the catalyst has a medium strong acid content of 0.05-2.0 mmol/g of catalyst, and a ratio of the medium strong acid content to the total acid content of 60-99%. When used in the catalytic conversion of alkyl aromatic hydrocarbons, the catalyst exhibits high reaction activity, low aromatic hydrocarbon loss rate.
