Process for conversion of propane to gasoline
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/sup 6/ and C/sup 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/sup 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.
