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

Article abstract of DOI:10.1246/cl.1998.519

A new kind of M_xO_y/SO₄^2--/H-form dealuminated β (DHβ) catalysts prepared here were applied to alkylation of isobutane with 1-butene. The group of M_xC_y/SO₄^2-/DHβ (M = Ti, Fe) catalysts has a lower rate of deactivation and higher selectivity of this alkylation than other group of Hβ and DHβ. It is proposed that the strong acid sites corresponding to the active sites for this alkylation can be formed by the interaction among DHβ, M_xO_y, and SO₄^2-.
