Abstract

PURPOSE: To remove the adove-mentioned NOx by reduction at low cost, by using the scale formed by heating the low carbon steel mateiral containing a specified amount of Mn at a specified temperature in an oxidizing atmosphere as the catalyst, passing the exhause gas of combustion to which NH3 or CO has been added through the above catalyst and using the waste catalyst as the raw material for iron manufacture.
