    摘要: A method of burning a fossil fuel and air with the emmission of an exhaust gas consisting essentially of atmospheric gases, carbon dioxide and water vapor and essentially free of carbon monoxide, hydrocarbons and nitric oxide, which comprises burning the fossil fuel at a temperature between 1000.degree. C. and 1500.degree. C. with less than the stoichiometric amount of atmospheric oxygen required for complete combustion of the fossil fuel to yield a combustion gas containing uncombusted fossil fuel, partially combusted fossil fuel, water vapor, carbon dioxide, carbon monoxide, and atmospheric nitrogen, said carbon dioxide and carbon monoxide being in the ratio of 100 parts carbon dioxide to between 1 and about 11 parts carbon monoxide; combining said combustion gas with a predetermined amount of an oxygen containing gas to give at least a 1% excess of the stoichiometric amount of oxygen for oxidizing the uncombusted and partially combusted fossil fuel and carbon monoxide; and passing the resulting mixture over a novel ceramic catalyst at a temperature between about 200.degree. C. and about 1000.degree. C. The usable heat energy of said combustion gas may be employed for work. The fossil fuel may also contain sulfur which is oxidized to sulfur trioxide by said catalyst in the presence of excess oxygen.

    摘要: This disclosure relates generally to processes for efficient incineration and conversion of the tail gas streams from sulfur recovery units containing sulfur compounds such as H2S, CO2, COS, CS2, and other sulfur species and sulfur vapors from S1 to S8 to SO2. The present disclosure describes the use of a combination of catalysts to achieve efficient oxidation of all reduced sulfur compounds as well as oxidation of CO and H2 to meet the industry emission requirements. The catalytic tail gas incineration process described herein can advantageously operate at lower temperatures, which in turn can represent a savings in reduced fuel gas costs.
