    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： The thermal stability of poly alpha-olefin (PAO) lubricant basestocks are improved by reacting an aromatic compound with the alpha-olefin oligomer. The PAO materials are prepared by oligomerization of olefins such as 1-decene in the presence of a Lewis acid oligomerization catalyst. The resulting lubricant basestock product exhibits high viscosity, viscosity index and low pour point in addition to the unique enhancement in thermal stability. The reaction between the PAO and the aromatic is carried out in the presence of a solid, cyrstalline alkylation catalyst identified by a specific X-ray diffraction pattern. The preferred catalyst for this purpose is the material known as MCM-22.

    摘要： High viscosity index, low pour point lubricants are produced by the oligomerization of a wax-derived lubricant fraction. The fraction may be produced from slack wax or de-oiled wax by hydroisomerization over zeolite beta or hydrocracking/isomerization over an amorphous catalyst followed by selective dewaxing, preferably by catalytic dewaxing over a highly shape selective zeolite such as ZSM-23. The preferred peroxides are ditertiary alkyl peroxides such as ditertiary butyl peroxide (DTBP) and are typically used at temperatures of 100.degree.-300.degree. C.

    摘要： Long chain alkyl substituted naphthalenes are produced by the alkylation of naphthalene with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite which contains cations having a radius of at least 2.5 .ANG.. Cations of this size may be provided by hydrated cations such as hydrated ammonium, sodium or potassium cations or by organoammonium cations such as tetraalkylammonium cations. The zeolite is usually a large pore size ze USY. The presence of the bulky cations in the zeolite increases the selectivity of the catalyst for the production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products.

    摘要： Turbine oils are produced from a distillate lube fraction by solvent extraction to remove aromatics, e.g., with furfural, then dewaxing and hydrofinishing to saturate residual aromatics. Treatment with an organic peroxide, such as ditertiary butyl peroxide (DTBP), increases viscosity to compensate for the viscosity loss during the hydrofinishing. Dewaxing may be solvent or catalytic dewaxing or both. Peroxide treatment also reduces cloud point.
