<p>A method is described for converting formaldehyde to a gaseous product mixture capable of reacting with nitrogen oxide which comprises reacting formaldehyde with nitrogen in the presence of a catalyst which is capable of promoting the reaction between formaldehyde and nitrogen at a temperature below about 1200 °F. The gaseous product mixture obtained in this manner is effective in reducing the nitrogen oxide content of combustion gases by mixing the gaseous product mixture with the combustion gas at temperatures from ambient temperature up to about 2000 °F.</p> |
