MxOy/SO42-/dealuminated zeolite beta (M=Ti,Fe) as novel catalysts for alkylation of isobutane with 1-butene

摘要

A new kind of MxOy/SO42-/H-form dealuminated beta (DH beta) catalysts prepared here were applied to alkylation of isobutane with 1-butene. The group of MxOy/SO42-/DH beta (M = Ti, Fe) catalysts has a lower rate of deactivation and higher selectivity of this alkylation than other group of H beta and DH beta. It is proposed that the strong acid sites corresponding to the active sites fbr this alkylation can be formed by the interaction among DH beta, MxOy, and SO42-. [References: 8]
