  • Patent number: 5427995
    Abstract: An alumina sorbent capable of adsorbing NOx and SOx from waste gases and being regenerated by heating above 650.degree. C. is made by incorporating an alumina stabilizing agent into the sorbent. A preferred method is to add the stabilizer when the alumina is precipitated. The precipitated powder is formed subsequently into a slurry, milled and spray dried to form the stabilized spheroidal alumina particles having a particle size of less than 500 microns. These particles are impregnated with an alkali metal or alkaline earth metal to form the stabilized sorbent. Alumina stabilizers include one or more of silica, lanthana, other rare earths, titania, zirconia and alkaline earths.

  • Patent number: 5411724
    Abstract: Aluminum can be removed from tetrahedral framework sites of zeolite frameworks and substituted with elements such as silicon, gallium, titanium or zirconium. The process involves three steps:(a) forming a mixture of the ammonium or alkaline metal form of the zeolite in the hydrated state and a crystalline ammonium fluoro-halo-metallate salt;(b) heating the mixture at elevated temperatures to remove the aluminum from the zeolite and to introduce the metal from the salt into the structure of the zeolitic component by solid-state reaction while forming a fluoro-halo-aluminate complex salt; and(c) removing the formed fluoro-halo-aluminate complex salt.

  • Patent number: 5403750
    Abstract: Affinity matrices useful for the chromatography and immobilization of biological materials and the method of preparing and using the same are disclosed. The affinity supports are based on hydrated polyurethane polymers which have been activated to provide a means for covalently attaching a variety of bioaffinity agents. The hydrated polymer matrices are characterized by their biocompatibility and resistance to nonspecific protein adsorption. Preferably, the prepolymers used to prepare the hydrated polymers are isocyanate-capped oxyethylene-based diols or polyols, at least 75% of said diols and polyols having a molecular weight of 7000 to about 30,000.

  • Patent number: 5397571
    Abstract: Disclosed is an improved method of extracting neem seeds. The method involves co-solvent extracting neem seeds with a solvent mixture of a nonpolar, aliphatic hydrocarbon solvent and a polar solvent to simultaneously remove the hydrophilic and hydrophobic extracts from the neem seeds. The method provides novel neem extract mixtures which contain both the hydrophobic and hydrophilic portion Of the neem seeds. The extract mixtures may be further extracted to yield an azadirachtin-containing solid product having greater than 10 weight percent of azadirachtin.

  • Patent number: 5395808
    Abstract: Porous bodies are produced which are suitable for use as supports for catalysts, including living cells, such as bacteria. The bodies have a significantly large average pore diameter of about 0.5 to 100 microns, (i.e. 5,000 to 1,000,000 .ANG.) and a total pore volume of about 0.1 to 1.5 cc/g with the large pores contributing a pore volume of from about 0.1 to 1.0 cc/g. The bodies are made by preparing a mixture of ultimate particles of bound clay, one or more optional ingredients such as inorganic binders, extrusion or forming aids, burnout agents, or a forming liquid, such as water. In a preferred embodiment, the ultimate particles are formed by spray drying.

  • Patent number: 5395600
    Abstract: A multicellular monolith converter body having a plurality of corrugated thin metal sheets or strips in alternating relation with a thin wire mesh or frame, and which monolith has a cell density up to 100 cells per square inch. These monoliths are useful under conditions where back-pressure is a critical factor, e.g., natural draft exhaust applications. These devices may have corrugated thin metal sheets coated with a refractory metal oxide, e.g., alumina, with or without a noble metal catalyst.

  • Patent number: 5382351
    Abstract: When a zeolite additive composition of a medium-pore zeolite with a Constraint Index from about 1 to about 12 and a silica to alumina mole ratio greater than about 12 is added to a conventional cracking catalyst dispersed in an inorganic matrix, the octane will be improved, but there will be a yield loss in the amount of gasoline produced. An improvement in that catalyst system is obtained by partially exchanging the medium-pore zeolite additive with cations from one or more elements of Group IA, Group IIA or Group IIIA excluding rare earths of the Periodic Table. The octane number of the gasoline-range product of an FCC process is still improved while the amount of the gasoline yield loss typically observed for such octane-enhancing additives is reduced.

  • Patent number: 5346389
    Abstract: This invention includes a multiple-stage combustion apparatus which can be used in a high-temperature environment, such as with a gas turbine. In particular, the invention includes a novel structure for the first stage of such apparatus, and a method of making that first stage. The first stage, which is an ignition stage, is a reactor formed of a metal strip which is coated with a catalyst on only one side. The strip is also corrugated with a herringbone pattern. The strip is then folded back and forth upon itself to form a reactor of a desired cross-section. The reactor has rows of channels that are formed between the layers of the metal. The single coated side of the metal defines the walls of the channels in every other row. The fuel-air mixture that flows through the coated channels is combusted. The fuel-air mixture that flows through the uncoated channels is not combusted, and cools the catalyzed surfaces.
