PCT No. PCT/DE84/00142 Sec. 371 Date Feb. 20, 1985 Sec. 102(e) Date Feb. 20, 1985 PCT Filed Jul. 11, 1984 PCT Pub. No. WO85/00300 PCT Pub. Date Jan. 31, 1985.In a process for reducing the NOx content of waste gases by a catalytic reduction of the NOx gases using a washable catalyst, a solution is to be provided, with which, while retaining the advantages of the procedure known from the German Offenlegungsschrift No. 3,107,117, this danger is avoided and which is suitable for use with a large range of waste gases, that is, which in particular is not restricted to nitric acid plants. This is accomplished owing to the fact that the reduction is carried out using unsaturated hydrocarbons at a temperature equal to or less than 180 DEG C.
