ABSTRACT:
An isoparaffin-olefin alkylation process is disclosed which improves alkylate quality by segregating the olefin feed into intermediate feedstreams which are enriched in propene, 1-butene, and/or 2-butenes with respect to the olefin feed, and alkylating these intermediate feedstreams in separate reaction zones at reaction temperatures specific to the olefin feed to increase the ratio of trimethylpentanes to dimethylhexanes in the resulting alkylate product.
