Abstract: A catalyst composition including imogolite and its use in hydrogen processing hydrocarbons are disclosed.

Abstract: An improved process for the production of a low density formed product of an activated alumina having a large macro-pore volume and an excellent abrasion resistance, which comprises mixing the starting solid material selected from an alumina powder being able to be re-hydrated and a mixture of the alumina and other solid material with water, said starting solid material having an average particle size of 1 micron to 35 micron and a quarter deviation of particle distribution of not more than about 1.5, forming the mixture of a solid material and water into various shapes, re-hydrating the formed product by keeping it under wetted atmosphere or in water, and calcining the resulting re-hydrated product.

Abstract: A process for the upgrading of synthesis gas is provided wherein olefin and oxygenated hydrocarbons, particularly alcohol and carboxylic acid, products predominate. The process includes contacting synthesis gas at elevated temperature and pressure in the presence of a catalyst comprising partially reduced ruthenium oxide and elemental gold. The products may be recovered and contacted with hydrogen at elevated temperature and pressure in the presence of a hydrogenation catalyst to yield alkanes, alcohols and esters useful for fuels.

Abstract: Cracking catalysts or catalyst supports prepared from mixtures comprising colloidal alumina, colloidal silica, a particulate weighting agent, and/or an active catalytic component possess excellent catalytic and physical properties. The catalysts in accordance with the invention also show excellent resistance to metal poisoning, and are also highly useful in non-cracking and/or hydroconversion processes.

Abstract: This invention is concerned with production and use of high surface area particulate matter by calcining a charge of clay mineral, feldspar, zeolite, coal ash, fly ash, pozzolan or volcanic ash for a time to develop fractures which increase the surface area of the particles. Vacuum calcining decreases the calcining time. The calcined matter desirably has an analysis including: calcium oxide, about 20-40 weight %; aluminum oxide, about 15-35 weight %; and silicon oxide, about 20-40 weight %.The calcined particulate matter can be used in the treatment of impure aqueous materials; the matter is denser than water and sludge settles rapidly and completely. The calcined matter interacts with heavy metal ions to form tightly bound sludge that is nonhazardous for landfill disposal. The calcined matter can be combined with conventual coagulants, flocculants, filter aids, or activated carbon to obtain a multipurpose treating agent.

Abstract: A composition of matter suitable for use as a sulfur sorbent. A fibrous silicate clay with randomly dispersed fibers is mixed with alumina and a copper-containing compound so that at least 20 weight percent of the finished sorbent is copper.

Abstract: A process for hydroisomerization of C.sub.4 -C.sub.7 paraffins with a nickel and/or cobalt synthetic mica-montmorillonite catalyst which has been pretreated with hydrogen at a temperature of at least 400.degree. C.

Abstract: A catalyst that is especially useful in the production of aromatic nitriles by a fluidized bed process comprises highly attrition-resistant microspherical particles of vanadia and an inert support and is prepared by spray drying an aqueous slurry of finely divided particles of vanadia and the support.
