摘要： There is provided a method and catalyst for removing catalyst-poisoning impurities or contaminants such as arsenic, iron and nickel from hydrocarbonaceous fluids, particularly shale oil and fractions thereof. More particularly there is provided a method of removal of such impurities by contacting the fluids with a copper-Group VIA metal-alumina catalyst. For example, a copper-molybdenum-alumina catalyst may be used as a guard bed material in a step preceding most refining operations, such as desulfurization, denitrogenation, catalytic hydrogenation, etc.

摘要： Ethylbenzene is produced by the alkylation of benzene with ethylene in the presence of an alkylation catalyst having a particular structure defined by its X-ray diffraction pattern. A preferred catalyst is the zeolite MCM-22. The process is typically carried out at a temperature of 300.degree. to 1000.degree. F. but the catalyst provides sufficient activity for the reaction to be carried out at temperatures below 700.degree. F. Liquid phase operation is preferred, giving a lower yield of polyethylated products. The use of the selected catalyst also results in a reduction of the xylene impurity level to values below 500 ppm in the product.

摘要： A blended mineral oil lubricant is made having a higher viscosity index than predicted by calculating the viscosity index from an ASTM standard method designated D 341-87 or by calculating the average of the actual VI based on the proportion of each component of the blend. The lubricant is treated with a peroxide compound, preferably an organic peroxide such as di-tertiary butyl peroxide to increase the viscosity index. The treated lubricant is blended with a lubricant of lower viscosity index to achieve a blended lubricant having an enhanced viscosity index. The lubricant charge stock and blending component can be a wax-derived lubricant fraction or a conventional light neutral or heavy neutral mineral oil.

摘要： Catalytic conversion of a C.sub.2 -C.sub.5 alkane, e.g., isobutane and/or isopentane, to isoalkenes, e.g., isobutene and/or isopentene, respectively, is undertaken in the presence of an aromatic recycle stream which provides the heat of reaction for the conversion which is endothermic, in the absence of hydrogen.

摘要： A novel oligomerization catalyst and process for upgrading olefins employing new synthetic catalyst of ultra-large pore crystalline material. The new crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units; and the porous crystalline material is impregnated with at least one oligomerization promoting metal, such as Groups VIIIA metals, preferably nickel.The new process is provided for catalytic oligomerization of olefin feedstock which comprises contacting the feedstock under catalytic conversion conditions with the metal-modified acid metallosilicate solid catalyst having the structure of MCM-41 with hexagonal honeycomb lattice structure consisting essentially of uniform pores in the range of about 20 to 100 Angstroms. The oligomerization reaction is very selective, especially when conducted at temperature of 60.degree. to 120.degree. C. Low severity reaction permits excellent conversion of lower olefins at pressure of about 100-13,000 kPa range and moderate space velocity.

摘要： Long chain alkyl substituted aromatic compounds, particularly alkylated naphthalenes, are produced by the alkylation of aromatics, e.g. naphthalene, with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of a zeolite alkylation catalyst, preferably a large pore size zeolite such as zeolite Y and in the presence of from about 0.5 to 3.0 weight percent water, preferably 1.0 to 3.0 weight percent. The use of the water co-feed increases the selectivity of the alkylation for the production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products and also increases activity and catalyst stability.

摘要： Alkylated aromatic functional fluids are prepared by alkylating a light cycle oil with an alkylating agent, such as an alpha C.sub.14 -olefin or coker gas oil, over a crystalline metallosiicate catalyst, preferably an aluminosilicate, including MCM-22, USY or an acid treated kaolin clay. The process produces an improved light cycle oil in which the heteroatom content of the oil is reduced and a high quality synthetic alkylated aromatic functional fluid base stock boiling above 600.degree.
