    摘要： A process for the production of an alkaline earth metal, aluminum-containing spinel/clay composition comprises: (a) combining (1) an acidic, aluminum-containing composition in which the aluminum is present in a positively charged species, and (2) a basic, alkaline earth metal-containing composition to form a gel mixture; (b) mixing the gel with kaolin clay to form a co-gel; and (c) calcining the co-gel mixture to form the alkaline earth metal, aluminum-containing spinel composition in a clay matrix. Alkaline earth metal, aluminum-containing spinel/clays having both high surface areas and very high attrition resistance, and processes for using spinel/clay compositions, e.g., as sulfur oxide and nitrogen oxide removal agent, are also disclosed.

    摘要： The present disclosure relates to a process and a process plant for desulfurizing a process gas comprising elemental sulfur, H 2 and water, comprising the steps of
    a. directing the process gas to contact a material catalytically active in hydrogenation to provide a hydrogenated process gas under effective hydrogenation conditions,
    b. cooling and phase separating the hydrogenated process gas, to provide a water condensate and a moisture reduced hydrogenated process gas,
    c. oxidizing the moisture reduced hydrogenated process gas after addition of a source of O 2 , to form an SO 2 rich process gas,
    d. catalytically oxidizing the SO 2 rich process gas to provide an SO 3 rich process gas
    e. hydrating the SO 3 in said SO 3 rich process gas to form H 2 SO 4 and condensing sulfuric acid and providing a desulfurized process gas substantially free of H 2 SO 4 and a liquid stream of concentrated sulfuric acid.
    This has the associated benefit of providing an SO 2 rich process gas of lower volume, compared to a process without intermediate withdrawal of water. If the process gas does not contain a sufficient amount of hydrogen, this may be added.

    摘要： A process where a gas, containing SO2 and O2 is brought in contact with a mixture of from 95% vol. to 50% vol. of activated carbon catalyst and from 5% vol. to 50% vol. of an inert filler material, where the SO2 is converted to H2SO4 on the activated carbon catalyst and is then washed from the activated carbon catalyst to obtain a H2SO4 solution.
