PROCESS FOR THE SELECTIVE DESULFURIZATION OF A MID RANGE GASOLINE CUT.

摘要

A full boiling range naphtha is concurrently fractionated and treated. The full boiling range naphtha streams is first subjected to simultaneous thioetherification and splitting into a light boiling range naphtha, an intermediate boiling range naphtha and a heavy boiling range naphtha in a distillation column reactor (10). The intermediate boiling range naphtha containing thiophene and thiophene boiling range mercaptans is passed on to a polishing hydrodesulfurization reactor (40) where a low sulfur, low olefin gas oil is concurrently fed to the polishing reactor (40) to insure that a liquid phase is present.
