Abstract: Highly stable and active catalysts are provided for the alkylation of aromatic hydrocarbons with C.sub.2 -C.sub.4 olefins. The catalysts are extruded composites of an acidic, crystalline aluminosilicate zeolite, e.g. Y zeolite, and a porous mineral oxide binder. The basic novel feature of the invention resides in the shape and size of the catalyst extrudates. By shaping the extrudates so as to give a high ratio of external surface area to volume, resistance to deactivation is found to be much improved, as well as activity and selectivity.

Abstract: Disclosed is a process for the removal of hydrogen from streams comprising olefinic compounds, such as streams from a polymerization reactor. At least a portion of the olefinic compounds are saturated with a substantial portion of the hydrogen present so as to effectively remove hydrogen from the stream. The saturated material formed can be then separated from unreacted olefinic compounds by use of a membrane separator and the olefinic compounds recycled to a polymerization zone for reaction.

Abstract: Synthetic lubricating oil having a high viscosity index, very low pour point, low viscosity at 0.degree.F, high thermal stability, high resistance to depolymerization, high flash point and very low carbon residue, is prepared by subjecting polymeric material of very high viscosity boiling above 175.degree.C, and obtained through polymerization of normal alpha-olefines having the general formula R-CH = CH.sub.2, wherein R is an alkyl radical containing from 2 to 16 carbon atoms, in the presence of a TiCl.sub.4 /polyiminoalane catalyst, in a substantially inert atmosphere which may contain hydrogen up to a manometer pressure of 1 kg/cm.sup.2, to thermal cracking at atmospheric pressure and in the temperature range of 300.degree.C to 420.degree.C at a contact time in the range of 5 minutes to 4 hours, and then distilling product so obtained under vacuum to a temperature which corresponds to a distillation temperature of 400.degree.C at atmospheric pressure, and finally subjecting the residue with a boiling point higher than 400.degree.C to catalytic hydrogenation.

Abstract: An improved process for hydrogenating organic compounds is provided in which a catalyst is employed that has a nickel surface area greater than about 70 m2/g and a sodium content less than 0.2 wt. percent based on the total weight of catalyst. Significantly improved activity is obtained with the nickelsilica catalyst of this invention particularly in conversion of benzene to cyclohexane, in reducing oxo aldehydes to alcohols, and hydrogenating olefin compounds to paraffins. The catalyst is prepared by coprecipitating nickel and silicate ions in the presence of a porous silica support under conditions of dilution that favor high surface areas and low inclusion of sodium in the catalyst.

Abstract: A catalytically hydrogenated naphtha stream containing less than 10 ppm by weight of sulfur is pyrolyzed without added hydrogen to a product including ethylene. Selectivity to ethylene is increased by adding a sulfur compound to increase the sulfur content to above 20 ppm by weight based on hydrogenated naphtha. Addition of the sulfur compound increases the quality of hydrogenated naphtha as a pyrolysis feedstock nearly to that of a C.sub.2 to C.sub.5 paraffin stream.
