A continuous catalytic process is described for converting olefinic feedstock comprising ethylene and C/sub 3/+ olefins to heavier liquid hydrocarbon product comprising the steps of prefractionating the olefinic feedstock to obtain a gaseous stream rich in ethylene and an olefinic stream containing C/sub 3/+ olefin; contacting a major portion of the C/sub 3/+ stream from the prefractionating step with shape selective medium pore zeolite oligomerization catalyst in a distillate mode catalytic reactor zone at elevated temperature and pressure. This is done to provide a heavier hydrocarbon effluent stream comprising distillate, gasoline and lighter hydrocarbons; fractionating the effluent stream to recover distillate, gasoline and C/sub 3/-C/sub 4/ hydrocarbon stream containing isobutane; further reacting isobutane from the C/sub 3/-C/sub 4/ hydrocarbon stream with a second portion of C/sub 3/+ olefin from the prefractionating step in an alkylation reactor zone in the presence of acid alkylation catalyst to produce C/sub 7/+ alkylate.
