ABSTRACT:
In a process for cleaning a waste gas containing various pollutants, the exhaust gas with the pollutants is introduced directly into a reduction reactor. In the reactor, the pollutants are reduced by ammonia. The catalyst used is iron oxide material or a mixed oxide material of iron oxide and chromium oxide, or a mixture of the mixture material of the mixed oxide material and the iron oxide material.
