Abstract: 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.

Abstract: 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.
