摘要： A metallic reforming catalyst, consisting of platinum and iridium or platinum, iridium and copper on a porous carrier provides excellent conversion of naphtha to C.sub.5.sup.+ product. A method of incorporating the metals or metal compounds on the carrier and preparing the finished catalyst using dimethyl sulfoxide is a novel procedure and provides unexpected catalytic properties. Novel reforming operations using these catalysts under moderate or severe conditions do not drastically alter the product yield.

摘要： An FCC or fluidized catalytic cracking process and apparatus for converting heavy metals laden crudes is disclosed. The heavy feed, conventional catalyst and an additive or vanadium getter contact the feed in a riser reactor. The additive is segregated from conventional FCC catalyst upstream of the conventional FCC regenerator. An elutriating, upflow riser reactor may be used with a coarse, rapidly settling getter. A fine, slowly settling getter may be used, with getter segregation achieved by using an elutriating cyclone on the riser outlet, an elutriating catalyst stripper, a sieve, or the like. The spent getter may be used once through, regenerated in a separate getter regenerator, or used as a source of fuel. Alumina and sponge coke are preferred getters.

摘要： An integrated refining scheme for hydroprocessing high boiling fractions such as gas oil and catalytically cracked cycle oils to produce premium quality distillates, especially jet fuels and naphthas suitable for reforming into high octane gasoline. In addition, unconverted, high boiling fractions suitable for processing by conventional refining techniques into high quality, low pour point lube base stocks are obtained. The integrated hydroprocessing comprises a first stage hydrocracking step employing an aromatic selective hydrocracking catalyst based on a large pore size acidic component such as amorphous alumina or silica alumina or a large pore size zeolite such as zeolite X or zeolite Y. The hydrocracking may be operated either in a naphtha directing mode under conditions of moderate to high severity or under conditions of low to moderate severity to produce a relatively higher proportion of product boiling in the middle distillate range. The unconverted fraction from the hydrocracking step is passed to a second step in which it is hydroprocessed over a zeolite beta catalyst with additional hydrogenation-dehydrogenation functionality. In this stage, the paraffins remaining in the feed are attacked by the zeolite beta to form isoparaffins and conditions may be controlled to favor hydroisomerization over hydrocracking so as to increase the yield of middle distillate product, especially of highly isoparaffinic jet fuels and diesel fuel.
摘要翻译：一种用于加氢处理高沸点馏分（如瓦斯油和催化裂解循环油）的综合精炼方案，以生产优质馏出物，特别是适用于重整为高辛烷值汽油的喷气燃料和石脑油。此外，获得了适用于通过常规精制技术加工成高质量低倾点润滑油基础油料的未转化的高沸点馏分。一体化加氢处理包括使用基于大孔径酸性组分如无定形氧化铝或二氧化硅氧化铝或大孔径沸石如沸石X或沸石Y的芳族选择性加氢裂化催化剂的第一阶段加氢裂化步骤。加氢裂化可以在中等至高严重度的条件下或在低至中等严重度的条件下以石脑油引导模式在中间馏分范围内产生相对较高比例的沸点产物。来自加氢裂化步骤的未转化的级分被传递到第二步骤，其中其在具有另外的氢化 - 脱氢官能团的沸石β催化剂上进行加氢处理。在这个阶段，剩余在饲料中的链烷烃被沸石β攻击以形成异链烷烃，并且可以控制条件以有利于加氢裂化加氢异构化，从而提高中间馏分产物，特别是高度异链烷烃喷气燃料和柴油燃料的产率。

摘要： The catalytic properties of a metal-containing shape selective crystalline silicate zeolite are significantly improved by converting said metal to an intermetallic compound. Thus, for example, zeolite beta containing the intermetallic component platinum zeolite demonstrates improved catalytic properties for dewaxing a hydrocarbon feedstock compared to zeolite beta containing platinum metal alone.

摘要： The acidity of a zeolite catalyst is reduced by calcination in an essentially water-free atmosphere at temperatures above 700.degree. C., preferably from 725.degree. to 800.degree. C., to reduce the alpha value to less than about 10 percent of its original value. The low acidity catalysts produced in this way may be used for conversions requiring low acidity, shape selective catalysis, including dewaxing. The calcined, low acidity catalysts exhibit improved dewaxing activity.
