Process and apparatus for removing NOx from gas streams
Abstract
Abstract Process and apparatus for reducing the NO x content of a gas stream containing NO x by reacting the gas stream with activated species. The activated species may be produced by providing a fluid reactant selected from HNCO, NH 3 , and H 2 NNH 2 and passing the fluid reactant across a catalyst. The activated species are believed to include free radicals selected from the group consisting of NCO, NH 2 , NH, H, N, OH, NC, and mixtures thereof. The activation step takes place out of contact with the gas stream, so the catalyst or other activated species generator is not exposed to the gas stream. The activation step allows the contacting step and subsequent reaction of the activated species and the NO x to proceed more quickly, more completely, or at a lower temperature than would otherwise occur without the activation step.
