    摘要: High purity benzene and high octane alkylaromatic gasoline can be obtained via a dual stage reforming process utilizing a non-acidic Group VIII metal containing microporous crystalline silicate catalyst in the first stage followed by first stage effluent treatment over acidic zeolite catalyst operating under conditions in the second stage to upgrade the first stage effluent in RON, in aromatic content or both.

    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 process for dewaxing a hydrocarbon feedstock with a relatively high pour point and containing paraffins selected from the group of normal paraffins and slightly branched paraffins and sulfur and nitrogen compounds which comprises subjecting said oil to hydrotreating in a hydrotreating zone operated at hydrotreating conditions sufficient to remove at least a portion of said sulfur and nitrogen compounds and subjecting said hydrotreated oil to catalytic dewaxing by contacting said oil with a catalyst comprising zeolite beta having a silica/alumina ratio of at least 30:1 and a hydrogenation/dehydrogenation component under isomerization conditions.
