Abstract

A method of reducing the NO content of a gas stream comprises contacting the gas stream with an amount of HNCO at a temperature effective for heat-induced decomposition of HNCO, said amount and temperature being effective for resultant lowering of the NO content of the gas stream, said solid agent being particulate and having a particle size of less than 90 [mu]m.

NO reduction using sublimation of cyanuric acid

Patent Perry, R A

This patent describes a method of reducing the NO content of a gas stream. It comprises: contacting the gas stream with an amount of HNCO at a temperature effective for heat induced decomposition of HNCO, the amount and temperature being effective for resultant lowering of the NO content of the gas-stream and the HNCO having been previously generated in gaseous form prior to being conducted into admixture with the gas stream.
NO reduction using sublimation of cyanuric acid

Patent Perry, R A

This patent describes a method of reducing the NO content of an exhaust gas stream generated by combustion. It comprises: contacting the exhaust gas stream generated by combustion with an amount of gaseous HNCO at a temperature effective for heat induced decomposition of HNCO. The amount and temperature being effective for resultant lowering of the NO content of the exhaust gas stream and the contacting being effected by adding gaseous HNCO directly to the exhaust gas stream.
System for NO reduction using sublimation of cyanuric acid

Patent Perry, R A

An arrangement for reducing the NO content of a gas stream comprises contacting the gas stream with HNCO at a temperature effective for heat induced decomposition of HNCO and for resultant lowering of the NO content of the gas stream. Preferably, the HNCO is generated by sublimation of cyanuric acid. 1 fig.
NO reduction using sublimation of cyanuric acid

Patent Perry, R

This patent describes a method of reducing the NO content of a gas stream comprising contacting the gas stream with HNCO in the presence of an amount of carbon monoxide effective to produce or regenerate H atoms, at a temperature effective for heat induced decomposition of HNCO and for resultant lowering of the NO content of the gas stream.
