    摘要： Disclosed are a process and apparatus useful for reclaiming sulfur-containing waste materials such as waste or spent sulfuric acid and acid tars.The sulfur-containing waste material is burned in a multi-stage combustion furnace having, in sequence, a rotary furnace containing heated coke, an intermediate combustion chamber and a secondary combustion chamber. The temperatures, gas flow rates and amount of added air are carefully controlled.A separation gas is produced having a high sulfur dioxide content which can be used in the sulfuric acid contact process. The separation gas is free of nitrous oxides, hydrocarbons and sulfur trioxide.

    摘要： A process for the oxidation of ammonia to hydrogen cyanide which comprises combining ammonia with a predetermined amount of oxygen and methane to produce hydrogen cyanide and water and passing the resulting mixture over a ceramic catalyst of the following empirical formula at a temperature between about 700.degree. and 1100.degree. C.:W.sub.k X.sub.n J.sub.(1-k-n) ZO.sub.(3.+-.m')Wherein:W is zirconium, tin or thorium or mixture thereof;X is an alkaline earth metal or mixture thereof;J is scandium, yttrium, a rare-earth element or mixture thereof;Z is a metal of the first transition series or a mixture thereof, at least 0.01% of said metal having an oxidation state other than +3;k is a number having a value of between 0 and about 0.1;m' is a number having a value of from 0 to about 0.26, provided m' has a value other than 0 when n has a value of 0; andn is a number having a value from 0 to about 0.51, provided when n has a value of 0, k has a value of between 0 and about 0.05. These mixed oxide catalysts can be used to catalytically oxidize organic compounds to various states of oxidation, ammonia, carbon monoxide, hydrogen, sulfur dioxide, and hydrogen sulfide, with oxygen, or carbon monoxide with water, sulfur dioxide or nitric oxide. The catalyst can also be employed in the catalytic removal of carbon monoxide, hydrocarbons, nitric oxides and sulfur dioxide from the exhaust gases of generating or heating plants and automobiles burning fossil fuels. In addition these catalysts can be employed to produce hydrogen cyanide from methane, ammonia and oxygen.

    摘要： A method is provided for removing ammonia from the sour water stream of a coal gasification process. The basic steps comprise stripping the ammonia from the sour water; heating the stripped ammonia to a temperature from between 400.degree. to 1,000.degree. F; passing the gaseous ammonia through a reactor containing a sulfided catalyst to produce elemental hydrogen and nitrogen; and scrubbing the reaction product to obtain an ammonia-free gas. The residual equilibrium ammonia produced by the reactor is recycled into the stripper. The ammonia-free gas may be advantageously treated in a Claus process to recover elemental sulfur. Iron sulfide or cobalt molybdenum sulfide catalysts are used.

    摘要： A catalyst chamber capable of converting the oxides of sulfur to hydrogen sulfide and the oxides of nitrogen to inert nitrogen and ammonia in the presence of a reducing atmosphere is inserted downstream of the boiler section of a fossil fuel burning power generator and there is added a system for extracting formed hydrogen sulfide from the fuel gas stream.After combustion of the primary fuel, typically sulfur bearing coal in excess air, a gaseous hydrocarbon such as methane, is combined with the products of combustion to at least scavenge the oxygen present to form a boiler effluent which ranges from slightly oxidizing to reducing in nature.Where the boiler effluent is reducing in nature, partial conversion of the oxides of sulfur and the oxides of nitrogen occur in the boiler, the balance occurring in the catalyst chamber.Where the gas is slightly oxidizing or only slightly reducing, make up reducing gas is added to the flue gas, either from an external reducing gas generator, or by removing a portion of the flue gas from the boiler section for combination with a vaporized hydrocarbon and air in a secondary boiler to generate the reducing gas for the reactions to take place in the catalyst chamber.The catalyst chamber is typically operated at a temperature from about 300.degree. to about 800.degree. F. In addition to eliminating air pollutants, boiler efficiency is increased.
