    摘要： A method and apparatus for catalytically processing a gas stream passing therethrough to reduce the presence of NOx therein, wherein the apparatus includes a first catalyst composed of a silver-containing alumina that is adapted for catalytically processing the gas stream at a first temperature range, a second catalyst composed of a copper-containing zeolite located downstream from the first catalyst, wherein the second catalyst is adapted for catalytically processing the gas stream at a lower second temperature range relative to the first temperature range, a hydrocarbon compound for injection into the gas stream upstream of the first catalyst to provide a reductant, and a reformer for reforming a portion of the hydrocarbon compound into H2 and/or oxygenated hydrocarbon for injection into the gas stream upstream of the first catalyst. The second catalyst is adapted to facilitate the reaction of reducing NOx into N2, whereby the intermediates are produced via the first catalyst reacting with NOx and hydrocarbons.

    摘要： This disclosure relates to a process for preparing a catalyst composition comprising (a) contacting a molecular sieve composition with a solution of a solvent and a solute under ion-exchange conditions to form an exchanged molecular sieve composition, wherein the solute comprises at least one of an amide compound, an imide compound, a strong proton donor, or any combination thereof, the solute has a solubility in the solvent of at least 0.05 g per 100 grams of the solvent, preferably at least 1 gram per 100 grams of the solvent; and (b) separating the exchanged molecular sieve from the mixture of the step (a).
