摘要： Process and apparatus for upgrading paraffinic naphtha to high octane fuel by contacting a fresh virgin naphtha feedstock stream medium pore acid cracking catalyst comprising MCM-22 zeolite under low pressure selective cracking conditions effective to produce increased yield of total C4-C5 branched aliphatic hydrocarbhons. The preferred feedstock is straight run naptha containing C7+ alkanes, at least 15 wt % C7+ cycloaliphatic hydrocarbons and less than 20% aromatics, which can be converted with a fluidized bed catalyst in a vertical riser reactor during a short contact period.The isoalkene products of cracking are etherified to provide high octane fuel components.

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： 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.

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： Long chain alkyl substituted naphthalenes are produced by alkylating naphthalene with an olefin or other alkylating agent with at least 6, and usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite having rare earth cations, and both ammonium and protonic species, associated with the exchangeable sites of the zeolite. The zeolite is usually a large pore size zeolite such as USY. The presence of rare earths and both ammonium and protonic species increases selectivity for production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products.

摘要： Olefins are converted to lower alkene hydrocarbon products, e.g., propene, butenes, and isoalkenes with zeolite MCM-22 catalyst. This catalytic conversion is particularly useful in the selective separation of linear olefins in mixed hydrocarbon streams, employing MCM-22 catalyst to convert these straight-chain unsaturated components to lighter products, particularly, C.sub.3 -C.sub.4 olefins. One potential application of this selective separation is in the removal of linear olefins from FCC gasoline.
