In a process for removing SOx and NOx from waste gases, SOx will quasi-completely be removed from the waste gases either in a first single step or in several steps, and this preferably by means of adsorption cokes (activated carbon) of an adsorptive capacity for SO2 of above 40 g SO2 per KG of coke, whereupon the thus pre-cleaned gas will be subjected to a secondary treatment after admixture of NH3 using catalysts of an absorptive capacity for SO2 of below 10 g SO2 per KG of catalyst, preferably below 5 g of catalyst, by reduction of NOx to N2.
