Abstract: Compositions comprising a component containing (i) an acidic oxide support, (ii) an alkali metal and/or alkaline earth metal or mixtures thereof, (iii) a transition metal oxide having oxygen storage capability, and (iv) a transition metal selected from Groups Ib and/or IIb of the Periodic Table provide NOx control performance in FCC processes. The acidic oxide support preferably contains silica alumina. Ceria is the preferred oxygen storage oxide. Cu and Ag are preferred Group I/IIb transition metals. The compositions are especially useful in the cracking of hydrocarbon feedstocks having above average nitrogen content.

Abstract: A process for the preparation of mixed oxide compositions of cerium oxide and at least one non-noble metal oxide is disclosed. The process involves contacting a salt solution containing a cerium (IV) salt with hydrogen peroxide and thereafter, treating the resulting solution with excess base to precipitate a mixed oxides. Mixed oxide compositions produced by the process maintain a high specific surface area after prolonged exposure to high temperatures.

Abstract: A dry zeolite containing composition is used in a method for removing grease and/or oil stains from the human body is disclosed. In accordance with the method, zeolites having an average particle size of about 0.5 mm or less provide superior performance to remove grease and oil stains from the skin. Stain removing activities of the zeolite compositions may be enhanced by the addition of an imide.

Abstract: A porous inorganic oxide carrier body for immobilizing living cells is prepared from inorganic oxide particles such as clay particles. The particles have an average particle size of from 0.01 to 20 microns, and the carrier body has a total pore volume of 0.05 to 1.0 cc/g and an average pore diameter of 50 to 700 .ANG., and has substantially no pore volume in the range of 800 .ANG. or greater. The carrier is prepared by forming a mixture containing the particles, a liquid medium and optional ingredients including zeolite and activated carbon, and forming the mixture into a shaped carrier body which may be optionally dried and calcined. Typical shapes of the carrier include spheres, cylinders, rings, honeycombs and shaped monoliths. Bacteria and other microorganisms immobilized on the carrier are useful for treatment of contaminated waste streams or contaminated vapors, or for other uses for which microorganisms are used such as the synthesis of chemicals.

Abstract: An improved method for the removal of stains from textiles is disclosed. The method involves the use of novel mixtures of zeolites and imides. The method of the invention provides superior performance in the removal of stains, especially those from animal wastes or fluids. The zeolite/imide mixtures are useful to remove stains from various textile fabrics and fibers, e.g. carpets, clothing, and upholstered goods.

Abstract: A method for making a honeycomb carrier body and product formed thereby in which a corrugated foil strip is provided having opposite side edges and corrugations oriented at an oblique angle to the side edges. The corrugated foil strip is folded on lines perpendicular to the side edges to provide a core body having fluid passages between opposite ends and a shaped periphery defined by parallel outside folds in the corrugated strip. The core body thus formed is inserted into a jacket tube so that folds at the core body periphery are in compressive contact with the jacket tube, and the periphery of the core body is joined to the jacket tube. Preferably, the corrugated foil strip is coated before the folding step, such as with an oxide layer, a catalytic coating or both, prior to the folding step.

Abstract: A powder composition of ceric oxide and a stabilizing non-noble metal oxide, such as zirconium oxide, mixed at the atomic level in complete solid solution. The powder is used to form washcoats for catalytic converters. The composition has high oxygen storage capacity and maintains an ultrafine crystallite size at high temperatures. The powder is formed by a spray pyrolysis process that includes atomizing a clear solution of cerium ions and ions of the non-noble metal into a fine mist that is passed rapidly through a furnace to form powder particles.
