    摘要： A catalyst for the oxidation of volatile organic compounds and carbon monoxide comprising manganese and alumina, such catalyst having been impregnated with a phosphorus compound. The presence of the phosphorus compound results in a significant oxidative conversion of both the volatile organic compounds and the carbon monoxide. The catalyst is especially useful for treating gaseous streams that emanate from industrial sources, such as wood pulp manufacturing plants. The manganese portion of the catalyst is preferably comprised of manganese compounds comprising a defect non-stoichiometric manganese oxide of the type β-Mn3O4+x, wherein x has the value of 0.1≦x≦0.25 in respect to about 80 to about 95% of all manganese atoms, and manganese aluminate in respect to the balance of the manganese atoms. The alumina portion of the catalyst is preferably comprised of high temperature forms of alumina of the type comprising α-Al2O3 and (α+δ+θ)-Al2O3.

    摘要： The present invention is directed to a metal-promoted zeolite beta catalyst useful in the selective catalytic reduction of nitrogen oxides with ammonia in which the zeolite beta is pre-treated so as to provide the zeolite with improved hydrothermal stability.The stabilized beta zeolite is provided by incorporating into the zeolite structure non-framework aluminum oxide chains. The aluminum oxide chains can be incorporated into the zeolite structure by a unique steaming regimen or by treatment with rare earth metals, such as cerium. The treatment process is unlike well-known methods of dealuminizing zeolites for the purpose of increasing the silica to alumina ratio. In the present invention, the non-framework aluminum oxide is characterized by FT-IR by a peak at 3781±2 cm−1, which when present, stabilizes the zeolite against further dealumination such as under oxidizing and harsh hydrothermal conditions.
