PURPOSE:To obtain a carbonaceous material for reduction of NOx having high activity and SO2 resistance by supporting a spinel type compd. contg. specified metals as a catalytic component on a carbonaceous material. CONSTITUTION:A spinel type compd. represented by a general formula AB2O4 (where A is Cu, Co or Ni and B is Al, Cr, Fe or Co) is supported on a carbonaceous material such as coal or coke. The resulting denitrating agent has high activity to the reduction and removal of NOx and the consumption of carbon by O2 coexisting with NOx is remarkably inhibited. Since the agent has improved SO2 resistance, denitration is stably and effectively carried out. |
