1. An alkylation apparatus comprising: a. a distributor adapted to distribute portions of an aliphatic feedstock comprising paraffin and mono-olefin of 8 to 18 carbon atoms per molecule; b. a reactor assembly comprising at least three alkylation reaction zones in series each containing solid alkylation catalyst and each having an inlet region and in fluid flow opposition through the catalyst, an outlet region adapted to contain reaction zone effluent; c. a heat exchanger between each of the alkylation reaction zones adapted to cool the reaction zone effluent of the preceding alkylation reaction zone by at least about 5° C.; and d. a trim alkylation reaction zone containing solid alkylation catalyst and adapted to receive reaction zone effluent from the last of the remaining alkylation reaction zones.
