Abstract
A thermally regenerable sorbent composition for removal of oxides of nitrogen from a gas stream wherein the sorbent consists essentially of about 15 to 35 wt. percent Fe, about 15 to 35 wt. percent Co and greater than about 5 wt. percent Na. The process for removal of oxides of nitrogen from a gas stream containing oxygen wherein the gas stream is passed in contact with the thermally regenerable sorbent composition described at a contact temperature of about 200.degree. C. to 400.degree. C. and is thermally regenerable by heating at a temperature of about 400.degree. C. to 550.degree. C. The process and composition is effective for gas streams where the oxides of nitrogen content is less than 2000 ppm and is particularly effective where the oxides of nitrogen content is about 50 to 1000 ppm. The composition and process is especially useful in removal of oxides of nitrogen from combustion gas effluents such as from furnaces and vehicles.
