Owen, H; Hsia, C H; Wright, B S

A continuous catalytic system is described for converting a fraction of olefinic feedstock comprising ethylene and C/sub 3/+ olefins to heavier liquid hydrocarbon product comprising: (a) means for prefractionating the olefinic feedstock to obtain a gaseous stream rich in ethylene and a liquid stream containing C/sub 3/+ olefin; (b) means for vaporizing and contacting the liquid stream from the prefractionating step with hydrocarbon conversion oligomerization catalyst in a catalytic reactor system to provide a heavier hydrocarbon effluent stream comprising distillate, gasoline and lighter hydrocarbons; (c) means for fractionating the effluent stream to recover distillate, gasoline and lighter hydrocarbon separately; (d) means for recycling at least a portion of the recovered gasoline as a liquid sorption stream to prefractionating step (a); and (e) means for further reacting the recycled gasoline together with sorbed C/sub 3/+ olefin in the catalytic reactor system of step (b).
