    摘要： A process for alkylating an isoparaffin with an olefin using a solid, particulate catalyst capable of adsorbing the olefin. The isoparaffin and the olefin are admixed to form a reactants stream in contact with catalyst particles at the upstream end of an adsorption zone; the reactants stream and catalyst particles are passed cocurrently through the adsorption zone without back mixing, at controlled relative velocities, so that a controlled amount of olefin is adsorbed onto the catalyst and removed from the reactants stream as the catalyst and hydrocarbons are passed cocurrently through the adsorption zone; reactants stream and catalyst particles having olefin adsorbed thereon are withdrawn from the downstream end of the adsorption zone and contacted in an alkylation reaction zone to alkylate the isoparaffin with previously adsorbed olefin; and the alkylation reaction product is recovered from the hydrocarbon effluent from the alkylation zone.
