摘要： A process for the conversion of H.sub.2 S to SO.sub.2 in a feed gas containing H.sub.2 S is effected by oxidation with air or oxygen at temperatures between 300.degree. and 900.degree. F. The oxidation is conducted in the presence of an extremely stable oxidation catalyst comprising an oxide and/or sulfide of vanadium supported on a non-alkaline porous refractory oxide. The preferred catalyst comprises between 5 and 15 wt.% V.sub.2 O.sub.5 on hydrogen mordenite or alumina. Hydrogen, carbon monoxide and light hydrocarbons present in the feed gas are not oxidized. The invention is especially contemplated for use in treating waste gases from geothermal steam power plants.

摘要： Electrolysis and catalytic thermochemistry are combined to decompose water while minimizing the energy demanded to accomplish the decomposition. The electrolyte is H2SO3 produced by supplying SO2 and the water to be decomposed to the electrolyzer. The H2SO3 is ionized and oxidized in the electrolyzer into SO4 and H ions and electrons. Hydrogen is derived from the negative electrode of the electrolyzer. The SO4 is combined with H to form H2SO4. The H2SO4 is removed from the electrolyzer to the thermochemical unit, concentrated and decomposed predominately into H2O, SO2 and O2. The SO2 is liquefied and thus separated from the O2 which is derived from the thermochemical apparatus. The liquid SO2 is vaporized and returned to the electrolyzer.

摘要： A process for treating metal pyrosulfites such as potassium, cesium, and rubidium pyrosulfites to obtain SO2 therefrom is disclosed. The pyrosulfite is reduced with a reducing agent such as hydrogen while in physical admixture with an inert, inorganic, refractory, particulate solid, a eutectic mixture of which with the desired metal sulfide has a melting point greater than the reduction zone temperatures, preferably greater than 1,650* F. Advantageously, the refractory solid for the reduction zone mixture is provided by introducing to the zone a pelletized admixture of the metal pyrosulfite with a hydrate of the refractory solid which, upon being heated to the reduction zone temperatures, will release water of hydration and be converted in situ to the refractory solid. Especially preferred is the use of pelletized admixtures of hydrous aluminum oxide and the metal pyrosulfite, the hydrous aluminum oxide being converted to alumina with the release of water when subjected to the reduction zone temperatures. The process can be employed with particular advantage where the pyrosulfite is obtained as a result of reacting SO2-containing gases with an aqueous absorbing solution of the corresponding metal sulfite to produce a spent absorbing solution containing dissolved metal bisulfite, and then recovering the metal bisulfite therefrom in the form of the corresponding metal pyrosulfite (e.g., by cooling the spent absorbing solution to crystallize out the pyrosulfite). The metal sulfide product obtained can be dissolved in water and the resulting solution treated with CO2 to provide hydrogen sulfide and the corresponding metal carbonate (which can be recycled to the SO2 absorption reaction). The H2S from the latter step may be mixed with the SO2 obtained from the reducing step and the mixture subjected to the Claus reaction to produce elemental sulfur and water.
