Abstract
This invention relates to an improved process for the alkylation of olefins in an alkylation unit feed stream in order to produce a higher yield of alkylate having a higher octane number, a lower acid consumption rate, and a lower energy consumption. Such a process involves passing a feed stream comprised of olefins and paraffins through a membrane so that the olefins are separated from the paraffins. In passing through the membrane, the olefins are facilitated in their transport by an isoparaffin sweep stream and together, the olefin/isoparaffin stream is passed into an alkylation reactor. Within the reactor, the olefins react with the isoparaffins to form alkylate.
