    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 improved method which provides for an extended cycle length in catalytic lube dewaxing of residual lube oil feedstocks and easier catalyst regeneration. The method may incorporate catalytically dewaxing a feedstock in a fixed bed reactor with or without product recycle, or a series of reactors with interreactor separation of vapors from liquids. Improved performance is achieved by operating the reactor at a temperature between about 490.degree. and about 620.degree. F., employing a high activity crystalline zeolite catalyst having an alpha value between about 50 and about 900 based on the zeolite and a space velocity sufficiently low to produce a dewaxed effluent of desired pour point and to maintain an average catalyst aging rate of less than about 2.degree. F. per day. This relatively low temperature operation allows catalyst performance to be restored by simple hydrogen reactivation.

    摘要: A combined process for treating heavy hydrocarbon feedstocks, such as resids that minimizes coke production and maximizes naphtha production, comprising the steps of thermally treating the feedstocks, in the absence of an added catalyst and either with or without hydrogen and steam, at a temperature of at least about 750.degree. F. (399.degree. C.) and under a pressure greater than about 400 psig to create significant chemical transformations without causing phase separation and consequent formation of sludge or a coke deposit; topping the thermally treated product to produce a distillate fraction and a bottoms fraction; coking the bottom fraction to produce gas, liquid products, and coke; and finally catalytically cracking the combined distillate fraction and liquid products to recover gas, gasoline, and light distillate products.

    摘要: Conversion of hydrocarbons is conducted over low acidity zeolites such as the sodium form of zeolite ZSM-5 to yield products like those produced by hydrocracking but with substantially decreased proportion of light hydrocarbons having one to four carbon atoms. (Sulfiding of sodium zeolites activates such sodium zeolites for the present purpose.) The hydrocarbon conversion is conducted with mixed phase charge (Trickle mode) under hydrogen pressure or with liquid phase charge in a liquid-full reactor.A catalyst composition comprising a metallic hydrogenation catalyst on a refractory support and an alkali metal crystalline zeolite.
