    摘要: A pervaporation element includes a ceramic monolith having an array of parallel channels separated by porous channel walls extending along an axial length of the monolith, and a functional membrane coating a first plurality of the porous channel walls along the axial length of the monolith. The functional membrane functions to separate a fluid into a retentate portion and a permeate portion. The porous channel walls coated by the functional membrane define a plurality of discrete through segments, where each of the discrete through segments are separated from one another by a plurality of uncoated porous channel walls. Fluid entering the discrete through segments is separated into a retentate portion that exits in substantial portion through the discrete through segments and a permeate portion that exits the ceramic monolith radially outward through the uncoated porous channel walls and through a skin of the monolith.

    摘要: Diamondoid compounds are concentrated in a solvent mixture containing at least 20% by weight of normal and slightly branched C.sub.5 -C.sub.30 paraffins by selectively converting the paraffins to lower boiling aliphatic hydrocarbons and separating the lower boiling aliphatics from the solvent mixture to yield a concentrated solvent mixture enriched in diamondoid compounds. Useful shape selective catalysts include zeolites having Constraint Indices from about 1 to about 12, such as ZSM-5 and MCM-22.

    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 high isoparaffinic jet fuels and diesel fuel.

    摘要: A method for suppressing light gas production in a cracking process by dispersing in the feed low concentrations of a highly siliceous material having high surface area and low acidity prior to cracking. Because of the high surface area-to-volume ratio of the particles, the catalyst acts as a free radical scavenger which reduces the amount of light gas produced by free radical-promoted reactions.
