Abstract
A process for the alkylation of aromatics with olefins using a solid catalyst is disclosed, wherein the olefin ratio and/or the maximum olefin concentration in the alkylation catalyst bed is maintained less than an upper limit. Such operation can decrease the catalyst deactivation rate and the formation of diphenylalkanes. This invention is applicable to processes for the production of a wide variety of commercially important alkylated aromatics, including ethylbenzene and cumene.
