The invention comprises a process for selectively oxidizing hydrogen in a mixture with other gaseous materials by contacting the hydrogen containing gas under oxidation conditions with a catalyst comprising a phosphate of a metal wherein the metal is selected from the group consisting of germanium, tin, lead, arsenic, antimony and bismuth.

Process and catalyst for dehydrogenation of organic compounds

Alkanes are dehydrogenated by passage through alternating dehydrogenation zones and selective oxidation zone(s), in which latter zone(s) hydrogen produced in the preceding endothermic dehydrogenation reaction is selectively oxidized to generate heat for the succeeding dehydrogenation reaction. New catalyst compositions are prepared comprising reduced and sulfided nickel crystallites on siliceous supports which have been treated with chromium compounds and oxidized to provide surface-anchored chromyl species. Also new catalyst compositions are prepared by sulfiding nickel-containing compositions with carbonaceous sulfur compounds such as dialkylsulfoxides. Another embodiment of the invention is catalyst and dehydrogenation therewith, in which pores having radius of 50 to 200 Angstroms occupy pore volume from 0.30 to 1.50 ml per gram of the support, and pores having radius of 20 to 50 Angstroms occupy pore volume less than 0.1 ml per gram of the support. In another embodiment, alkanes are dehydrogenated using as catalyst a metal or metal compound having dehydrogenating activity supported on alkali-treated alumina.

Process and apparatus are provided for oxidation of oxidation of organic compounds in which a reaction zone is provided, containing an open space and a bed of solid granular catalyst, an organic feedstock and oxygen are passed in gas phase through the open space and then into contact with the catalyst bed, and reaction products are removed from the open space after relatively less contact with the catalyst, and from at least one other location after relatively greater contact with the catalyst. Greater yield of desired product may be obtained in such operation than in operation where all of the reaction products are removed after the greater contact with the catalyst.

Catalytic oxidation of alkanes

Barium peroxide in which has been incorporated a transition metal compound is used as a catalyst for the oxidative dehydrogenation of organic compounds in the presence of terminal oxidants.

Catalytic dehydrogenation of alkanes

A process for the direct catalytic oxidation of methane to methanol comprises separately contacting chromium chemically bound to the oxygen of a metal oxide support surface with (1) methane and (2) oxidant. The support may comprise silica, alumina, magnesia, titania, or zirconia.

Chromia on metal oxide for the oxidation of alkane to alcohol

Aluminophosphates containing manganese in the structural framework are employed for the oxidation of alkanes, for example the vapor phase oxidation of methane to methanol.

New manganese catalyst for light alkane oxidation

A process for the direct catalytic oxidation of methane to methanol comprises chromium chemically bound to the oxygen of a metal oxide catalytic support surface. The support may comprise silica, alumina, magnesia, titania, or zirconia.

Chromia on metal oxide catalysts for the oxidation of methane to methanol

Process is provided for oxidation of organic compounds in which a reaction zone is provided, containing an open space and a bed of solid granular catalyst, an organic feedstock and oxygen are passed in gas phase through the open space and then into contact with the catalyst bed, and reaction products are removed from the open space after relatively less contact with the catalyst, and from at least one other location after relatively greater contact with the catalyst. Greater yield of desired product may be obtained in such operation than in operation where all of the reaction products are removed after the greater contact with the catalyst.

Silicometallates containing iron in the structural framework are employed as catalysts for the oxidation of hydrocarbons or oxygenated hydrocarbons, for example the vapor phase oxidation of methane to methanol.
