摘要： A process for producing lubricant oils of low pour point and high viscosity index by first carrying out a partial dewaxing of a lubricant base stock in an initial catalytic dewaxing operation, followed by a selective dewaxing step. The initial catalytic dewaxing step is carried out using a large pore, high silica zeolite dewaxing catalyst such as high silica Y or zeolite beta which dewaxes by isomerizing the waxy components of the base stock to less waxy brance chain isoparaffins but the severity of the operation is controlled so as to effect only a partial removal of the waxy components. Further removal of the waxy components is effected during the subsequent dewaxing step which is selective for the removal of the more waxy n-paraffin components, leaving the branched chain isoparaffins which contribute to a high VI in the product. The selective dewaxing step may be either a solvent, e.g. MEK dewaxing operation or a catalytic dewaxing using a highly shape selective zeolite such as ZSM-22 or ZSM-23. The severity of the initial catalytic dewaxing operation may be controlled so as to effect a net increase in the content of isoparaffins and because of the selective nature of the solvent dewaxing step, this increased isoparaffins concentration may be retained, producing a product of high VI. The pour point of the feedstock is preferably reduced during the initial catalytic dewaxing step to a value which is no lower than 10.degree. F. and preferably no lower than 20.degree. F., above the target pour point for the products. Generally, this will entail a reduction of at least 10.degree. F. and preferably at least 20.degree. F. in the pour point of the feed.

摘要： A process is disclosed for improving the Viscosity Index of a hydrocarbon lubricating oil comprising the steps of providing a flow reactor having separate first and second inlet ports for the separate co-injection of lubricating oil and an organic peroxide, charging said lubricating oil and said organic peroxide of said flow reactor through said first and second inlet ports respectively, controlling the relative flowrates of said lubricating oil and organic peroxide reactants together with the total volumetric flowrate through said flow reactor to maintain a flow regime which favors diffusional mixing between said organic peroxide and said lubricating oil, and maintaining said organic peroxide and said lubricating oil under conversion conditions including temperatures of between about 50.degree. and 300.degree. C. and pressure sufficient to maintain said lubricating oil and said organic peroxide substantially in the liquid phase. Controlling the flow regime to favor diffusional rather than convective mixing between the lubricating oil and the organic peroxide has surprisingly been found to markedly enhance Viscosity Index improvement.

摘要： A process for production of alkyl tertiary alkyl ethers in C.sub.4 + hydrocarbon streams rich in isoolefins, typically containing catalyst deactivating amounts of dienes and/or compounds containing heteroatoms. The process is especially advantageous in extending the cycle length for the zeolite catalyzed etherification of isoolefins in C.sub.4 + FCC gasoline by reducing catalyst aging. It has been discovered that if hydrogen is cofed with the alkanol and C.sub.4 + isoolefin rich feedstreams to an etherification reaction catalyzed by acidic zeolite wherein the zeolite has been impregnated with a noble metal the rate of catalyst aging or deactivation is substantially lowered. The process is especially effective, i.e., catalyst aging is particularly reduced, when hydrogen is cofed to an etherification reaction using acidic zeolite Beta catalyst containing palladium.

摘要： This application discloses critical parameters, including process conditions and catalysts which effect the alpha:beta ratio of alkylated naphthalene isomers. The use of low alkylation temperatures and of low acidity zeolite catalysts (e.g. steamed USY and zeolite beta) lead to an increase in the alpha:beta ratio. The alkylated naphthalene fluids with higher alpha:beta ratio exhibited significantly enhanced product qualities, including thermal and oxidative stabilities.

摘要： A process for upgrading aliphatic feedstocks containing lower 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. A new process is provied for catalytic oligomerization of lower olefin component in paraffin-containing mixed aliphatic feedstock which comprises contacting the feedstock under catalytic conversion conditions with 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 about 40.degree. to 250.degree. C., yielding branched intermediate olefins. Low severity reaction permits execellent conversion of lower olefins at pressure of about 100-13,000 pKa range and moderate space velocity. Oligomers of propene produced over MCM-41, when reacted under cracking/disproportionation conditions yield a propylene-rich mixture which is separated as a C.sub.3 stream, and C.sub.6 + isoalkenes are recovered in good yield.

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.
