摘要： A crude oil is upgraded by thermal treatment at a temperature of at least 400.degree. C. under at least autogenous pressure and preferably from 100 to 1000 psig for about 20 to 30 minutes in order to increase the proportion of distillable components in the crude. The improvement is attributed to alkylation of lower molecular weight components, especially aromatics, by alkyl groups derived from the high boiling component of the crude. The process reduces the nondistillable residue and enables subsequent processing to be carried out with lower gas and coke make. The process may be operated with a whole crude or a topped crude as feed.
摘要翻译：原油通过在至少400℃的温度下至少自生压力，优选100至1000psig的温度下升级约20至30分钟来升级，以增加粗品中可馏出组分的比例。改进归因于通过衍生自粗品的高沸点组分的烷基将低分子量组分，特别是芳族化合物烷基化。该方法减少了不可补充的残留物，并且可以用较低的气体和焦炭进行后续处理。该方法可以以整个原油或顶部原油作为进料进行操作。

摘要： A moderate pressure hydrocracking process in which a highly aromatic, substantially dealkylated feedstock having a boiling point in the range between 300.degree. and 650.degree. F. is processed directly to high octane gasoline by hydrocracking over a catalyst, preferably comprising a large pore size, crystalline alumino-silicate zeolite hydrocracking catalyst such as zeolite Y together with a hydrogenation-dehydrogenation component. The feedstock which is preferably a light cut light cycle oil has an aromatic content of at least 50, usually at least 60 percent and an API gravity not more than 25. The hydrocracking typically operates at 600-1000 psig at moderate to high conversion levels to maximize the production of monocyclic aromatics which provide the requisite octane value to the product gasoline.

摘要： A moderate pressure hydrocracking process is disclosed in which substantially dealkylated heavy distillate feedstocks are processed directly to high octane gasoline over a catalyst, preferably comprising a crystalline silicate zeolite hydrocracking component having a Constraint Index less than 2. The bottoms fraction produced from the contacting may be passed to an FCC unit for further processing. In another embodiment, the substantially dealkylated heavy distillate feedstock may be fractionated into a lighter boiling stream and a heavier boiling stream for better ease of processing.

摘要： An improved process for catalytically dewaxing low nitrogen content hydrocarbon oils, such as distilled hydrocracker bottoms which normally form by-product naphtha of variable, but poor octane quality. The improvement is achieved by doping the low nitrogen content oil with a small amount of high nitrogen content gas oil, resulting in a by-product naphtha having a clear research octane of about 90, which octane is relatively insensitive to adjustment of pour point during processing.

摘要： A new xylene isomerization process which is capable of converting ethylbenzene and non-aromatic exhaustively while selectively converting xylenes to thermal equilibrium in mixed EB/xylene feeds is proposed. The new process employs a two component catalyst system; each of the components contains a strong hydrogenation metal and a zeolite. The zeolite of each of the two components differs from the other in its selectivity for xylene isomerization and its capacity to deethylete ethylbenzene. That selectivity for xylene isomerization is described by xylene diffusion properties of the zeolite. In one embodiment of the invention, ZSM-5 of greater than 1 micron crystal size and an alpha value of greater than 100 in a first component and ZSM-5 of less than 1 micron crystal size and an alpha of less than 100 in a second catalyst component satisfy the diffusion properties which allow for the exhaustive conversion of ethyl benzene and non-aromatics and the selectivity for xylene isomerization of typical xylene isomerization feeds. In a preferred embodiment, the feed is cascaded over the first component and then the aforementioned second component.

摘要： A process for making a lubricant oil of low pour point which comprises a) catalytically dewaxing a lube boiling range feedstock in the presence of hydrogen over a dewaxing catalyst comprising an intermediate pore size zeolite in the hydrogen or decationized form during a dewaxing cycle in which the temperature is progressively increased to maintain a substantially constant product pour point to produce a lubricant oil product of improved oxidation stability. The feedstock is sequenced during a dewaxing cycle from a heavy feed to a lighter feed in order to avoid contacting the lighter feed with the catalyst in its most active conditions.

摘要： A process for dispersing or dispersing relatively large crystallites of an agglomerated Group VIII noble metal species present on a porous inorganic support is disclosed. The process includes contacting the agglomerated noble metal species, e.g., palladium or platinum, present on the support, e.g., alumina, silica or a zeolite such as ZSM-5 from which at least a major portion of any extraneous matter such as coke or other residue has previously been removed, with nitric oxide (NO) alone or in admixture with a source of halogen such as Cl.sub.2 and thereafter removing sorbed nitrogen oxide(s) and halogen, if present. The thus treated metal-loaded catalyst demonstrates substantially increased benzene hydrogenation activity (BHA) compared to the same catalyst prior to treatment indicating significant dispersion/redispersion of the metal crystallites as smaller crystallites.
