Abstract: A process for removing NOX from combustion gases by adsorption includes the step of desorbing the NOX when the adsorbent is saturated to create an effluent. The effluent is mixed with a reducing gas and passed over a reduction catalyst which reduces the NOX to water and elemental nitrogen. The resultant harmless gas is discharged to the atmosphere.

Abstract: The process of this invention will remove acid rain precursors, sulfur oxides (SOX) and nitrogen oxides (NOX) by catalytically reducing the NOX to water and elemental nitrogen and the SOX to either H.sub.2 S or elemental sulfur as desired. The process employs specific catalysts in the heteropoly acid or salt group and the spinel or inverse spinel group. The process conditions achieve an oxygen-free environment and reduction is effected with stoichiometric to 100% excess above stoichiometric H.sub.2 or H.sub.2 and CO as reducing gas. Temperatures can be 200.degree. to 900.degree. C. with the lower temperature range being favored space velocity can be 2000 to 20,000 and still achieve 95+% abatement. The only product of the reaction which must be disposed of is saleable elemental sulfur.

Abstract: A heat source, may be on a high speed vehicle, may be cooled by transferring thermal energy from the heat source to an endothermic fuel decomposition catalyst in order to heat the catalyst to a temperature sufficient to crack or dissociate at least a portion of an endothermic fuel stream. The endothermic fuel is selected from the group consisting of normal paraffinic hydrocarbons and methanol. The heated endothermic fuel decomposition catalyst is contacted with the endothermic fuel stream at a liquid hourly space velocity of at least about 10 hr.sup.-1 to cause the endothermic fuel stream to crack or dissociate into a reaction product stream.

Abstract: The process of this invention will remove from acid rain essentially all of both the sulfur oxides (SOX) and nitrogen oxides (NOX) by catalytically reducing the NOX to water and elemental nitrogen and the SOX to either H.sub.2 S or elemental sulfur as desired.

Abstract: A catalyst undercoat (wash-coat) material comprising a plurality of stable, highly porous, co-precipitated agglomerated microcrystalline comprised of integral admixture of alumina and at least one lanthanide. The co-precipitated material may be converted to a slurry and used as an undercoat or wash-coat atop a prefabricated low surface area support. Alternatively, the co-precipitated material may be compressed or extruded into various geometric forms and these can be used as a support and as such serve both as the support and the undercoat.

Abstract: Methanol is produced by passing a mixture of hydrogen and one or more carbon oxides into contact with at least two beds (converters) of catalyst arranged in series, the beds of catalyst being operated at increasing temperature levels in the direction of flow of the mixture. The mixture is then cooled by indirect heat-exchange and passed into contact with at least one further bed of catalyst.

Abstract: A catalyst particularly useful in the production of methanol can be made by preparing a solution of copper and zinc nitrates, the ratio of copper to zinc being from 1:1 to 8:1 and then precipitating the copper and zinc by the addition of ammonium carbonate or ammonium bicarbonate. After the precipitated material has been agglomerated and calcined, a copper oxide-zinc oxide catalyst, low in sodium and sulfur is obtained.

Abstract: The invention is directed to an integrated process for reducing the SO.sub.2 content of sulfuric acid plant off gases by (1) passing the SO.sub.2 -containing feed gas to the process over a specially defined multistage oxidation catalyst to convert SO.sub.2 to SO.sub.3, (2) absorbing the SO.sub.3 in water to form H.sub.2 SO.sub.4 and (3) scrubbing the off gases with aqueous hydrogen peroxide and/or sulfur-containing peroxy acids. At least the final oxidation stage of the process employs a supported CsVO.sub.3 or RbVO.sub.3 catalyst which is activated with cobalt or nickel sulfate and promoted with alkali metal sulfates, potassium aluminum sulfate or chromium potassium sulfate.
