Benzene upgrading reformer integration

摘要

A process and apparatus are disclosed for the production of gasoline from a C4- fuel gas containing ethene and propene and catalytic reformate containing C6 to C8 aromatics. The C4- fuel gas is contacted with debutanized catalytic reformate over a zeolite catalyst under process conditions to convert ethene and propene in the C4- fuel gas to C5+ aliphatic and aromatic hydrocarbon gasoline and to convert C6 to C8 aromatics in the reformate to C7 to C11 aromatic hydrocarbon gasoline. Reformer fractionation system containing debutanizer column and separator stabilizes effluent gasoline and recycles unconverted light aromatics.
