ABSTRACT:
A multi-step hydrocarbon conversion process for producing gasoline from propane is disclosed. Propane is passed into a dehydrogenation zone and the entire dehydrogenation zone effluent is then passed into a catalytic condensation zone wherein propylene is converted into C.sub.6 and C.sub.9 hydrocarbons. The condensation zone effluent, a stripper overhead stream and an absorber bottoms stream are commingled and then separated into vapor and liquid portions. The liquid is passed into the stripper, and the vapor portion is contacted with stripper bottoms liquid in an absorber. The absorber overhead stream is contacted with liquid propane in a second absorber to remove C.sub.6 hydrocarbons and is then recycled to the dehydrogenation zone. Depropanizing a portion of the stripper bottoms yields the liquid propane and a gasoline product.
