    摘要： 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.

    摘要： 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.

    摘要： The inclusion of salts of rubidium or cesium or mixtures thereof in a catalyst comprised of copper and zinc oxides and optionally manganese oxide or manganese and cobalt oxides and a stabilizer such as chromic, ceric, magnesium or aluminum oxides results in higher yields of C.sub.1 to C.sub.6 alkanols and lower production of hydrocarbons in the effluent from the catalytic reaction environment. The reactant gases passing over the catalyst comprises hydrogen and carbon monoxide and optionally carbon dioxide if economically advantageous.

    摘要： 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.

    摘要： 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.
