This patent describes an alkylation apparatus containing an inventory of catalyst wherein hydrocarbon feed mixture and alkylation catalysts are reacted to produce an effluent comprising a hydrocarbon phase and a catalyst phase. It includes heat exchanger means, having a catalyst inlet, a catalyst outlet and a drain outlet, for cooling catalyst passing therethrough; reactor means, having an upper end portion and a lower end portion, for reacting hydrocarbon feedstock and catalyst to produce a reaction effluent comprising a hydrocarbon phase and a catalyst phase; first conduit means in fluid flow communication between the catalyst outlet of the heat exchanger means and the lower end portion of the reactor means for conducting cooled catalyst from the heat exchanger means to the reactor means; second conduit means in fluid flow communication between a source of hydrocarbon feedstock and the lower end portion of the reactor means for conducting the hydrocarbon feedstock to the reactor means; settler vessel means, having an upper end portion, a lower end portion and a medial portion, and located at a relative elevation above the heat exchanger means, for separating the reaction effluent from the reactor means into a catalyst phase in the lower end portion of the settler vessel and a hydrocarbon phase above the catalyst phase in the settler vessel.
