    摘要: This disclosure relates to a catalyst composition comprising (a) a crystalline MCM-49 molecular sieve; and (b) a binder comprising at least 1 wt. % of a titanium compound. In one aspect of this disclosure, the titanium compound comprises at least one of titanium oxide, titanium hydroxide, titanium sulfate, titanium phosphate, or any combination thereof. In another aspect of this disclosure, the catalyst composition further comprises a crystalline MCM-22 family molecular sieve comprising at least one of MCM-22, MCM-36, MCM-49, MCM-56, ITQ-1, ITQ-2, ITQ-30, PSH-3, ERB-1, SSZ-25, or any combination thereof. In other embodiments, this disclosure relates to a process for preparing the catalyst composition of this disclosure, the process comprises (a) providing the crystalline MCM-49 molecular sieve and the binder comprising at least 1 wt. % of a titanium compound to form a mixture; and (b) forming the mixture into the catalyst composition. In a preferred embodiment, the forming step comprises extruding. In yet other embodiments, this disclosure discloses a process for alkylating an aromatic hydrocarbon with an alkylating agent to produce an alkylated aromatic product by contacting the aromatic hydrocarbon and the alkylating agent with the catalyst composition.
