    • An integrated process for treating pyrolysis gasolines, including: feeding the pyrolysis gasoline to a first stage wherein the pyrolysis gasoline is substantially depentanized and acetylene and diolefins are reacted with hydrogen to produce an effluent having a reduced acetylene and diolefin content; and feeding the effluent to a second stage, wherein the second stage comprises a catalytic distillation hydrotreating process. The second stage may include a first catalytic distillation reactor system comprising a first distillation reaction zone containing a first hydrogenation catalyst, and the process may further include treating a C 6 -boiling material in the first distillation reaction zone to react sulfur compounds with hydrogen to produce hydrogen sulfide, the treated C 6 material being concurrently separated as a second overheads from C 7 and heavier material by fractional distillation, the C 7 and heavier material being removed from the first distillation reaction zone as a first bottoms.
    • 一种用于处理热解汽油的综合方法,包括:将热解汽油进料到第一阶段,其中热解汽油基本上被去离子化,乙炔和二烯烃与氢气反应以产生具有降低的乙炔和二烯烃含量的流出物; 并将流出物进料到第二阶段,其中第二阶段包括催化蒸馏加氢处理方法。 第二阶段可以包括包含含有第一氢化催化剂的第一蒸馏反应区的第一催化蒸馏反应器系统,该方法还可以包括处理第一蒸馏反应区中的C6沸腾物质以使硫化合物与氢反应以产生氢 硫化物,被处理的C6材料通过分馏作为来自C7和较重材料的第二塔顶同时分离,作为第一底部从第一蒸馏反应区中除去C7和更重的材料。
