PCT No. PCT/US85/00770 Sec. 371 Date Dec. 16, 1985 Sec. 102(e) Date Dec. 16, 1985 PCT Filed Apr. 26, 1985 PCT Pub. No. WO85/05102 PCT Pub. Date Nov. 21, 1985.A process is disclosed for converting a feedstock containing ethylene to produce heavier hydrocarbons in the gasoline or distillate boiling range including the steps of contacting the olefins feedstock with a first siliceous crystalline molecular sieve at an elevated temperature and relatively low pressure under conditions which maximize the conversion of ethylene to C3-C4 olefins and C5+ hydrocarbons, separating C3-C4 olefins from the C5+ hydrocarbons, and contacting the separated C3-C4 olefins with a second siliceous crystalline molecular sieve at moderate temperatures under conditions favorable for conversion of the C3-C4 olefins to heavier hydrocarbons in the gasoline or distillate boiling range.
