摘要： A light cracked naphtha is treated to convert mercaptans to sulfides and saturate dienes and then subjected to destructive hydrodesulfurization (HDS) to convert the organic sulfur compounds to hydrogen sulfide. The recombinant mercaptans formed by reaction of hydrogen sulfide and olefins at the outlet of the HDS are generally heavier than the light cracked naphtha is fractionated in admixture with a heavy cracked naphtha. A low sulfur content light cracked naphtha is produced as an overheads and the major portion of the mercaptans leave with heavy cracked naphtha as bottoms. It also advantageous to pass the heavy cracked naphtha through the HDS in admixture with the light cracked naphtha, since the recombinant mercaptans formed with the heavy cracked naphtha olefins (which displace some of the lower mercaptans which would form the light cracked naphtha olefins) will be even higher boiling and easier to separate by fractionation.
