<p>PURPOSE:To enable high-efficiency denox in wide and low temp. range for use by using an excellent effect of NaN3 to remove NOx adn using a denox agent excellent in contact efficiency of NaN3 and NOx, to improve handling property and safeness and to miniaturize a denox device by using a granular denox agent, and moreover, to effect denox economically advantageously since this method requires no catalyst, and further, to obtain a denox agent excellent in porosity and contact efficiency which gives high denox efficiency by a simple process. CONSTITUTION:NaN3 granules 7 having improved binding force by addition of an org. binder is used as the denox agent. NOx is removed by bringing the NaN3 granules into contact with the objective gas to be treated. These granules 7 can be obtd. by adding the bionder to a NaN3 aq. soln., pouring this soln. into a die, and drying.</p> |
