摘要： A process for simultaneously desulfurizing and dewaxing raw, untreated, high sulfur-containing wide-cut petroleum oil fractions to produce desulfurized middle distillate oils of low pour point with a minimum cracking of the raw fraction to gases which comprises contacting the raw fraction with hydrogen and a catalyst comprising a hydrogenating component and faujasite on an amorphous support. A particularly preferred catalyst consists of 95 wt.% based on total catalyst of NiO/MoO.sub.3 on an amorphous silica/alumina support and 5 wt.% of nickel-exchanged faujasite.

摘要： An asphalt-containing mineral oil is deasphalted by contacting the oil with a liquid hydrogen sulfide deasphalting solvent for a time sufficient to remove a substantial portion of the asphalt from the oil. Utilization of liquid hydrogen sulfide as the deasphalting solvent is capable of giving high yields of deasphalted oil. In contrast to the use of aliphatic solvents for deasphalting, the hydrogen sulfide readily mixes with the heavy feed even at relatively low temperatures.
摘要翻译：含沥青的矿物油通过使油与液体硫化氢脱沥青溶剂接触一段足以从油中除去大部分沥青的时间而脱沥青。利用液体硫化氢作为脱沥青溶剂能够提供高产量的脱沥青油。与使用脂肪族溶剂进行脱沥青相比，硫化氢即使在相对较低的温度下也容易与重质进料混合。

摘要： A process for hydrotreating middle distillate fraction petroleum feed stocks wherein hydrogen requirements for the hydrotreater are reduced by first passing the feed stock and steam to a steam hydroconversion zone over a dual function catalyst comprising molybdenum on a chromium supported on ferric oxide support or on a high surface area alumina support. In the steam hydroconversion zone a portion of the feed reacts with the steam to produce hydrogen via a steam reforming reaction. This hydrogen is used in situ to saturate a substantial portion of the olefins and remove some of the sulfur compounds present in the feed stock, thereby partially refining same. The partially refined feed is then passed to a hydrotreating zone for further treatment with greatly reduced hydrogen requirements in said hydrotreating zone.
摘要翻译：一种用于加氢处理中间馏分馏分石油原料的方法，其中通过首先使原料和蒸汽通过双重功能催化剂将蒸汽加热转化到蒸汽加氢转化区，减少加氢处理器的氢需求，所述双重功能催化剂包含在负载在氧化铁载体上的铬上的钼或高表面积氧化铝载体。在蒸汽加氢转化区中，一部分进料与蒸汽反应，通过蒸汽重整反应产生氢气。这种氢原位使用以使大部分烯烃饱和并除去存在于原料中的一些硫化合物，从而部分地将其纯化。然后将部分精制的进料进入加氢处理区进行进一步处理，在所述加氢处理区中氢气需求大大降低。
