摘要： The pour point and/or cloud point of the lube fractions comprising a waxy hydrocarbon feedstock containing straight and branched chain paraffins is reduced by contacting the feedstock in a dewaxing zone, preferably in the presence of added hydrogen, with a dewaxing catalyst comprising (1) an intermediate pore crystalline molecular sieve having a pore size between about 5.0 Angstroms and about 7.0 Angstroms and (2) a large pore crystalline molecular sieve having a pore size above about 7.0 Angstroms and typically selected from the group consisting of silicoaluminophosphates, ferrosilicates, aluminophosphates and Y zeolites. A hydrocarbon fraction of reduced paraffin content is recovered from the effluent of the dewaxing zone. Preferred intermediate pore crystalline molecular sieves are silicalite and a ZSM-5 type zeolite. Preferred large pore crystalline molecular sieves are silicoaluminophosphates such as SAPO-5 and ammonium exchanged and steamed Y zeolites.

摘要： A hydrocarbon conversion catalyst useful for converting hydrocarbon feeds to midbarrel products is prepared by extruding a mixture of an inorganic refractory oxide component and a crystalline aluminosilicate zeolite having cracking activity to form extrudates which are broken into particles normally ranging in length between 1/16 and 1/2 inch. The extruded particles are then calcined in the presence of steam at a water vapor partial pressure greater than about 2.0 p.s.i.a., preferably greater than about 5.0 p.s.i.a. The calcination step is carried out in the presence of sufficient steam for a sufficient amount of time at a sufficient temperature to convert the crystalline aluminosilicate zeolite in the extrudates into an ultrahydrophobic zeolite having a unit cell size between about 24.20 and about 24.45 Angstroms and a sorptive capacity for water vapor less than about 5 weight percent of the zeolite at 25.degree. C. and a p/p.degree. value of 0.10.

摘要： A waxy hydrocarbon feedstock is converted into a high quality lube oil stock of reduced pour point by hydrodewaxing the feedstock in the presence of molecular hydrogen and a hydrodewaxing catalyst under conditions such that the pour point of the feedstock is reduced by selectively converting waxy paraffins into lower molecular weight hydrocarbons. At least a portion of the effluent from the hydrodewaxing zone is then passed to a hydrocracking zone where it is contacted with a hydrocracking catalyst under conditions such that a further reduction in pour point is effected and the overall conversion of components boiling above about 650.degree. F. to components boiling at or below about 650.degree. F. in the hydrodewaxing and hydrocracking steps combined is no more than about 20 percent by volume, preferably no more than about 10 percent by volume.

摘要： A process for alkylating aromatic hydrocarbons with C.sub.2 to C.sub.4 olefins and for transalkylating alkyl or poly-alkylaromatic compounds with an aromatic hydrocarbon. A major portion of the aromatic hydrocarbon is recycled to the alkylation zone while the remainder thereof and poly-alkylaromatic hydrocarbons are subjected to transalkylation in a separate transalkylation zone. Mono-alkylaromatics produced in the alkylation zone are separated from the other reaction products prior to transalkylation.

摘要： Y Zeolites are prepared with rare earth cations and Group VIII metal cations exchanged thereinto, such zeolites being especially useful in hydrocracking catalysts. The zeolites of the invention are prepared by exchanging a sodium Y zeolite with cations of one or more rare earth elements followed by a calcination, an ammonium ion exchange, and a Group VIII metal cation exchange. The resultant zeolite is not only highly active for catalytically promoting hydrocracking reactions but is also, after use in hydrocracking environments resulting in coke deposition, essentially completely regenerable by combustion of the coke.
