ABSTRACT:
A continuous method and apparatus for contact of olefin with paraffin in the presence of HF catalyst to produce alkylate in which about one half of the olefin feedstock is passed to each of two riser reactors with product effluent from both reactors entering a common settling vessel with return of settled HF catalyst proportioned between the two reactors and the paraffin feedstock provided as fresh or alkylate fractionator side stream recycle to one reactor and as reaction product recycle from the settler to the other reactor.
