  • Patent number: 7951742
    Abstract: A gas stream containing nitrous oxide and ammonia is contacted with a catalyst composition containing a zeolite. N2O is reduced to N2 and H2O at low temperatures in a highly efficient manner. Ammonia-mediated reduction of nitrous oxide can be effectuated from gas streams having N2O concentrations as low as 1%. The gas stream may also contact a catalytic composition selective for the reduction of NOx. In this way, N2O and NOx treatment may be effectuated in a single process stream.

  • Patent number: 7727499
    Abstract: The present invention is directed to a method for removal by oxidation of the excess ammonia (NH3) gas (“ammonia slip”) resulting from flue gases that have been subjected to selective catalytic reduction (SCR) for reduction of nitrogen oxides (NOx) with ammonia. More specifically, the inventive method uses an ammonia oxidation catalyst consisting of a zeolite, one or more precious metals, and a base metal compound, to catalyze the oxidation of both ammonia and carbon monoxide (CO), while minimizing the formation of nitrogen oxides (NOx). The present invention is useful in treating flue and exhaust gases.

  • Publication number: 20070072766
    Abstract: 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 ?-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 ?-Al2O3 and (?+?+?)-Al2O3.
