Claim:
A process unit for production of alkylate gasoline, comprising: a) a nozzle having an orifice that dispenses one or more recirculated streams comprising an ionic liquid catalyst into a chamber in the nozzle, wherein the chamber of the nozzle houses a center piece from which one or more external recirculated streams flow towards the orifice; and wherein the center piece is in the center of the nozzle; b) a dip tube, inserted into the center piece and within a flow of the one or more external recirculated streams, for introducing a hydrocarbon feed stream comprising an olefin to the orifice at a distance from the orifice that is within 25 times a diameter of the orifice; c) a throat connecting the chamber in the nozzle to an alkylation zone where alkylate gasoline blending components are produced; and d) an inlet on the side of the nozzle that feeds an internal recirculated stream from the alkylation zone to the chamber of the nozzle.
