Progress in Selective Hydrodesulfurization Processes of FCC Naphtha

It is well known that sulfur removal from FCC naphtha can be achieved by hydrodesulfurization(HDS),but the accompanying decrease of octane number is a significant loss due to the saturation of olefins in the traditional process.Selective HDS processes are very efficient and widely applied.In this paper,research progress in selective HDS processes at home and abroad was introduced.
