    摘要： The sulfur content of liquid cracking products, especially the cracked gasoline, of the catalytic cracking process is reduced by the use of a sulfur reduction catalyst composition comprising a porous molecular sieve which contains a metal in an oxidation state above zero within the interior of the pore structure of the sieve as well as a cerium component which enhances the stability and sulfur reduction activity of the catalyst. The molecular sieve is normally a faujasite such as USY. The primary sulfur reduction component is normally a metal of Period 3 of the Periodic Table, preferably vanadium. The sulfur reduction catalyst may be used in the form of a separate particle additive or as a component of an integrated cracking/sulfur reduction catalyst.

    摘要： Relatively heavy and relatively light lube chargestocks are dewaxed in two parallel, separate reactors. The reactor used for dewaxing the relatively light chargestock contains a crystallize zeolite having pore openings defined by: (1) a ratio of sorption of n-hexane to o-xylene, on a volume percent basis, of greater than 3, which sorption is determined at a P/P.sub.o of 0.1 and at a temperature of 50.degree. C. for n-hexane and 80.degree. C. for o-xylene and (2) by the ability of selectively cracking 3-methylpentane (3MP) in preference to the doubly branched 2,3-dimethylbutane (DMB) at 1000.degree. F. and 1 atmosphere pressure from a 1/1/1 weight ratio mixture of n-hexane/3-methyl-pentane/2,3-dimethylbutane, with the ratio of rate constants k.sub.3MP /k.sub.DMB determined at a temperature of 1000.degree. F. being in excess of about 2, e.g., natural and synthetic ferrierite, ZSM-22, ZSM-23, ZSM-35 and mixtures thereof. The reactor used for dewaxing the relatively heavy chargestock contains a crystalline aluminosilicate zeolite having pore openings defined by: (1) a ratio of sorption of n-hexane to o-xylene, on a volume percent basis, or less than 3, which sorption is determined at a P/P.sub.o of 0.1 and at a temperature of 50.degree. C. for n-hexane and 80.degree. C. for o-xylene, (2) the abiilty of selectively cracking 3-methylpentane (3MP) in preference to the doubly branched 2,3-dimethylbutane (DMB) at 1000.degree. F. and 1 atmosphere pressure from a 1/1/1 weight ratio mixture of n-hexane/3-methyl-pentane/2,3-dimethylbutane, with the ratio of rate constants k.sub.3MP /K.sub.DMB determined at a temperature of 1000.degree. F. being less than about 2, and (3) a Constraint Index value of greater than about 1, e.g., ZSM-5, ZSM-11, ZSM-5/ZSM-11 intermediate and mixtures thereof.

    摘要： A method of preparing aromatics processing catalysts which comprises incorporating a noble metal with a member or members of a useful class of zeolites, with such incorporation occurring after zeolite crystallization, but prior to final catalyst particle formation, i.e. extrusion into particles. Said useful class of zeolites is characterized by a silica to alumina mole ratio of at least 12 and a Constraint Index in the approximate range of 1 to 12.
