A solid catalyst alkylation process that wets catalyst particles with the alkylation substrate prior to introducing the catalyst particles to a liquid phase alkylation reactor is disclosed. A vapor stream from the wetting step that comprises the alkylation substrate and a reactor effluent stream comprising product alkylate and excess alkylation substrate are both passed to the product recovery zone, which recovers the alkylate product and recycles the alkylation substrate. Routing the vapor stream and the reactor effluent stream together to the product recovery zone minimizes pressure imbalances, ensures steady catalyst flow, and minimizes equipment costs. This process is applicable to alkylation processes that produce motor fuels.
