Abstract
A novel catalyst for alkylating an alkene with an alkane to give an alkylate product has been developed. The catalyst comprises a refractory inorganic oxide on which is dispersed a Group VIII metal, a metal cation and the reaction product of a metal halide and bound surface hydroxyl groups of the refractory inorganic oxide. The catalyst is characterized in that the Group VIII metal is concentrated in an outer layer of the catalyst particle.
