Abstract
An improved HF alkylation process comprising, in series, HF and isoparaffin flow and parallel injection of at least two different olefins into a vertically extended reaction zone coupled with recycle of some of the alkylation hydrocarbon effluent to each point of olefin introduction into the alkylation zone. The improved alkylation system allows minimum sized fractionation and extremely high isoparaffin/olefin ratios with temperature control of the reaction at each olefin injection.
