ABSTRACT:
A process for the systematic treatment of exhaust gases which comprises the steps of injecting a neutralizing absorbent and an auxiliary agent into the exhaust gas and passing the exhaust gas through a filter which has been precoated with the auxiliary agent, as used above, whereby the neutralizing absorbent and the auxiliary agent are permitted to deposit as a layer on the precoated filter and are able to collect the acidic gas components and dust in the exhaust gas and blowing ammonia into the emitted purified exhaust gas so that nitrogen oxides in the exhaust gas are reduced, in the presence of a denitrating catalyst, into nitrogen gas.
