Abstract: The present invention discloses aqueous methods for enhancing the acid sites of fluid catalytic cracking (FCC) catalysts. The methods comprise the steps of contacting an FCC catalyst, either spent or fresh, with an aqueous solution comprising water, an inorganic acid substantially free of chloride and aluminum. The acid is preferably sulfurous or sulfuric acid. The aluminum is provided by an aluminum source selected from the group consisting of the alumina trihydrates and aluminum oxide. Chloride contamination of the aluminum source should be minimal, preferably less than about 1000 ppm chloride, more preferably less than about 200 ppm chloride. The pH of the aqueous solution is adjusted to about 3-12 by the addition of a sufficient quantity of ammonium hydroxide. The FCC catalyst is added to this solution, preferably with stirring, in a weight ratio of about 1 part catalyst to about 1-10 parts water to prepare an aqueous slurry. Upon stabilization of the pH of the aqueous slurry, enhancement of the acid sites of the catalyst is achieved and the catalyst may be separated from the slurry and, if desired, washed. This simple, aqueous process reduces the level of many metal poisons on the FCC catalyst and produces a catalyst having an enhanced number of acid reaction sites.

Abstract: The instant invention relates to a method of preparing highly dispersed supported Group VIII metal catalysts. The instant invention further relates to the redispersion of sintered or agglomerated supported Group VIII metal catalysts. The process comprises the formation of supported Group VIII metal-phosphorus intermediate compounds followed by the treatment of these supported Group VIII metal-phosphorus compounds in an inert atmosphere at a temperature in the range of about 400.degree. C. to about 750.degree. C., preferably, about 550.degree. C. to about 700.degree. C., most preferably from 630.degree.-700.degree. C. The composition resultant from the dispersion heating step will form the highly dispersed, supported Group VIII metal catalysts by decomposition when reacting with an oxygen containing atmosphere, e.g. air, or reacting with water.

Abstract: The performance of phosphorus-vanadium-oxygen catalysts useful for the conversion of saturated aliphatic hydrocarbons to maleic anhydride is dependent on the controlled calcination of the catalyst precursor. Phosphorus-vanadium-oxygen catalysts are prepared by mixing phosphorus and vanadium compounds to form precursors containing tetravalent vanadium, and calcining the precursors in an oxidizing atmosphere until a controlled level of pentavalent vanadium has been achieved, and then calcining the precursors in an inert atmosphere to higher temperatures to provide catalysts with the desired oxidation levels that are promptly active, so that valuable manufacturing facilities are not required to "activate the catalyst."

Abstract: A catalyst support comprised of alumina and aluminum phosphate is prepared by the hydrolysis of an aluminum alkoxide such as aluminum sec-butoxide with an aqueous solution of phosphoric acid. The alumina-aluminum phosphate prepared in accordance with the invention is a stable material which can be readily formed for use as a support for catalysts useful in a number of hydrocarbon conversion processes. For example, the aluminaaluminum phosphate support may be impregnated with various combinations of cobalt, nickel, tungsten and molybdenum for use as a catalyst for the desulfurization and denitrogenation of both light and heavy petroleum fractions. The support material may also be combined with zeolitic materials for use in hydrocracking or catalytic cracking or combined with noble metals for use in the reforming of petroleum feedstocks.

Abstract: Surface stabilized active alumina having significantly increased thermal stability is made by incorporating 1-20%, preferably 218% by weight PO4-ion (calculated on the weight of the calcined composite) in alumina having an essentially pseudoboehmitic structure. The stabilized active alumina retains its surface area and consequently its activity for prolonged periods under high temperature exposure, for example at 900* C without material deterioration.

Abstract: Processes and a catalyst for the cycloaddition of an olefin, such as C2 to C4 olefins like, ethylene, propylene and butylene, to a biomass derived compound, such as dimethylfuran, furan, methylfuran. The catalyst has a relatively low silica to alumina ratio of around 25 compared with conventional catalysts which have a ratio greater than 1000. The catalyst has phosphorus and may be a beta zeolite. Such a catalyst can be used to generate a high yield of bio-based para-xylene.
