    • Paraffin alkylation using solid, particulate catalyst is carried out by preparing an alkane-catalyst mixture in a wash zone, passing the alkane-catalyst mixture to a plug flow reactor where a minor amount of olefin is introduced to contact the alkane-catalyst mixture and react to form alkylate and the alkane-catalyst-alkylate mixture is passed through the reactor with a minimum of back mixing to restrict the reaction of alkylate with olefin, thus substantially preventing polymerization. The alkane-catalyst-alkylate mixture, substantially free of olefin is passed to a disengaging zone where the liquid is removed and the solid particulate catalyst is recovered and returned to the wash zone for recycle. The alkane is present in the reactor in sufficient molar excess to react substantially all of the olefin. Any unreacted isoalkane is recycled to the reactor with make-up isoalkane added to maintain the molar excess. The preferred catalyst is an acid washed silica treated with antimony pentafluoride and more preferably treated with alkane at low temperature, e.g. -30.degree. to -160.degree. C.
    • 使用固体颗粒催化剂的石蜡烷基化通过在洗涤区中制备烷烃 - 催化剂混合物进行,将烷烃 - 催化剂混合物通过活塞流反应器,其中引入少量的烯烃以接触烷烃 - 催化剂混合物并反应 以形成烷基化物,烷烃 - 催化剂 - 烷基化物混合物以最少的反混合通过反应器以限制烷基化物与烯烃的反应,从而基本上防止聚合。 基本上不含烯烃的烷烃 - 催化剂 - 烷基化物混合物被传送到去除液体的脱离区域,并且将固体颗粒催化剂回收并返回到洗涤区域进行再循环。 烷烃以足够的摩尔过量存在于反应器中以使基本上所有的烯烃反应。 任何未反应的异烷烃被再循环到反应器中,加入补充的异烷烃以保持摩尔过量。 优选的催化剂是用五氟化锑处理的酸洗二氧化硅,更优选在低温下用烷烃处理,例如, -30℃至-160℃

    • A process for hydrotreating petroleum fractions early in the refining process by employing catalyst prepared as components of distillation structures or as contained beds of catalyst in atmospheric distillation columns and or side draw columns. For example, a crude petroleum is hydrotreated by taking side streams from an atmospheric distillation column and the vacuum gas oil from a vacuum distillation column which are individually fed to separate desulfurizations, preferably in distillation column reactors containing a hydrodesulfurization catalyst. The overheads from each of the distillation column reactors is returned to the atmospheric column and the bottoms from each distillation column reactor is withdrawn as hydrotreated product. The process may also be used for upgrading the effluent from a fluid catalytic cracking unit, preferably operated as a catalytic distillation reactor.
    • 一种在精炼过程早期加氢处理石油馏分的方法,其中采用制备为蒸馏结构的组分的催化剂或作为常压蒸馏塔和/或侧馏分塔中的催化剂床。 例如,通过将来自常压蒸馏塔的侧流和来自真空蒸馏塔的减压瓦斯油,分别进料到单独的脱硫,优选在含有加氢脱硫催化剂的蒸馏塔反应器中,将粗油加氢处理。 将每个蒸馏塔反应器的塔顶馏出物返回至大气柱,并将来自每个蒸馏塔反应器的塔底物作为加氢处理产物取出。 该方法还可用于将来自流化催化裂化装置的流出物升级,优选作为催化蒸馏反应器操作。
