ABSTRACT:
Tetrahedrally charged clays have been found to be active, regenerable catalysts in detergent alkylation, both as delaminated and pillared clays. The pillared saponites and beidellites are especially favored in forming detergent range alkylates using olefins as the alkylating agent to afford products with high monoalkylation selectivity and high linearity. Catalysts can be regenerated by a benzene wash or, after severe deactivation, by a carbon burn.
