    摘要： A bottoms fraction of fuels hydrocracking which boils above about 600.degree. F. and contains at least 10 wt. % aromatics is converted to a reduced aromatics lube/base stock product over a catalyst comprising a crystalline material which exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams anhydrous crystal at 50 torr and 25.degree. C. and a-hydrogenation-dehydrogenation functionality, preferably palladium, under high pressure conditions sufficient to reduce the aromatics content to about 10 wt. %. The bottoms fraction is dewaxed prior to high pressure hydroprocessing over a catalyst comprising HZSM-5 to reduce the pour point of the fraction to about 20.degree. F. Typically, the bottoms fraction is produced in a moderate pressure fuels hydrocracking process over a bifunctional amorphous catalyst.

    摘要： Petroleum wax feeds are converted to high Viscosity Index lubricants by a two-step hydrocracking-hydroisomerization process in which the wax feed is initially subjected to hydrocracking under mild conditions with a conversion to non-lube range products of no more than about 30 weight percent of the feed. The hydrocracking is carried out at a hydrogen pressure of at least 1000 psig using an amorphous catalyst which preferentially removes the aromatic components present in the initial feed. The hydrocracked effluent is then subjected to hydroisomerization in a second step using a low acidity dicarboxylic acid-treated zeolite Beta or mordenite catalyst which effects a preferential isomerization on the paraffin components to less waxy, high V.I. isoparaffins. The second stage may be operated at high pressure by cascading the first stage product into the second stage or at a lower pressure, typically from 200 to 1000 psig. The second stage catalyst is preferably a noble metal containing zeolite Beta catalyst which is treated with oxalic acid to give a low Alpha Value, typically below 10. The second stage is carried out at relatively low temperature, typically from 600.degree. to 650.degree. F. with a 650.degree. F.+ conversion in the range of 10 to 20 weight percent of the second stage feed but with high selectivity for isomerization of the paraffins. A final dewaxing step to target pour point may be used with relatively low loss, typically no more than 15 weight percent, during this dewaxing. The final products typically have V.I. values in excess of 130 and usually in the range of 140 to 155 and are characterized by exceptional stability.

    摘要： Light cycle oil (LCO) is upgraded to a low sulfur gasoline by co-processing the LCO with a cracked, sulfur-containing olefinic naphthas by hydrodesulfurization followed by treatment over an acidic catalyst comprising zeolite beta with a metal hydrogenation component such as molybdenum. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. The zeolite beta catalyst is active for conversion of the higher boiling portions of the feed to products of low sulfur content in the gasoline boiling range.

    摘要： A polycyclic aromatic is contacted with an alkyl-substituted single ring aromatic, such as toluene, o-, m- or p-xylene or mesitylene, over a catalyst comprising a zeolite, such as zeolite beta, USY or ZSM-5 to alkylate the polycyclic aromatic. The polycyclic aromatic can be a fused polynuclear aromatic, e.g. phenanthrene, or an assembly of two or more cyclic systems, e.g. biphenyl. The polycyclic aromatic can also include carbocyclic systems such as fluorene and naphthalene or heterocyclic systems such as benzothiophene and dibenzothiophene. The polycyclic aromatic can be derived from a cycle oil, coker gas oil, extract of lubricant solvent refining or crude distillate fraction. The transalkylating agent can be derived from a reformate, pyrolysis gasoline or coker naphtha.
