ABSTRACT:
Light aliphatic streams containing C.sub.4 - olefins are upgraded to C.sub.5 + gasoline in a two-stage process. In the first stage, olefins are oligomerized to C.sub.5 + olefinic gasoline. Unreacted light aliphatics including ethylene as well as light oligomerization byproducts are then charged to a second stage aromatization zone. Catalysts useful for both stages include medium pore zeolites.
