Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: High viscosity index, low pour point lubricants are produced by reacting an iso-paraffinic component, preferably with significant mono- and di-methyl chain branching, with an olefinic reactant in the presence of a free radical generator such as an organic peroxide, preferably ditertiary butyl peroxide. The isoparaffinic reactant is preferably obtained by the isomerization of a waxy feed such as slack wax over a zeolite beta isomerization catalyst, preferably Pt/zeolite beta. The olefinic reactant is preferably a distillate fraction produced by the oligomerization of low molecular weight olefins e.g., C.sub.3 to C.sub.5 olefins, produced by oligomerization over an intermediate pore size zeolite oligomerization catalyst such as ZSM-5.
