MULTISTAGE ALKYLATION PROCESS

摘要

In a multistage process, a relatively unreactive paraffinic substrate is alkylated in a primary stage while a more reactive aromatic substrate is alkylated in a secondary state wherein at least a portion of th e effluent from the primary stage is used as a diluent in the secondary stage. The alkylation reaction in each stage is catalyzed by an ac id catalyst which is adsorbed on a particulate solid support.
