Abstract (en)
The filter has on one base at least three zones with catalysts A, AB, B, where the first zone with catalyst A is separated from the second zone with catalyst B by a middle zone AB. It is significant that the catalyst of each middle zone AB is a composition of adjacent to the middle zone catalysts of A and B zones. <IMAGE>
