摘要： An integrated process for he isolation of benzene contained within a fluid catalytically cracked naphtha is disclosed wherein a C6 fraction containing a benzene concentrate is subjected to etherification with alcohol (e.g. methanol and/or ethanol) to convert the C6 isoolefins to ethers which are separated by fractional distillation. If desired the ethers may be dissociated to the isoolefins and alcohol. The remaining material in the benzene concentrate may then be treated to remove olefins and organic sulfur compounds so that the benzene may be removed by solvent extraction. Alternatively the benzene in the remaining material may be subjected to hydrogenation.

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.
摘要翻译：处理轻质裂解石脑油，将硫醇转化为硫化物，饱和二烯，然后进行破坏性加氢脱硫（HDS），将有机硫化合物转化成硫化氢。在HDS出口处通过硫化氢和烯烃的反应形成的重组硫醇通常比轻质裂化石脑油与重质裂解石脑油混合分馏更重。产生低硫含量的轻质裂化石脑油作为塔顶馏出物，硫醇的主要部分以重的裂解石脑油为底部。由于与重质裂解石脑油烯烃（其将形成轻质裂化石脑油烯烃的一部分低级硫醇取代）形成的重组硫醇将是重要的硫醇与轻质裂化石脑油混合，所以将重质裂解石脑油与HDS混合也是有利的甚至更高沸点，更容易通过分馏分离。
