    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： 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： Zeolite Y and other faujasite type zeolites are made stable to acid by calcination in a steam-containing atmosphere with a slow, controlled heating rate in the temperature range at which chemically bound water in the zeolite is given off, generally from 500.degree. C. to 650.degree. C. The stabilized product may be extracted with acid to produce a zeolite having a higher silica:alumina ratio. The high silica forms of zeolite ZSM-20 which may be produced by this method are novel materials.
