A deNOx catalyst was prepared by wash-coating a cobalt ion exchangedZSM-5 zeolite together with an alumina binder on a cordierite honeycomb structure. A few types of the Co-ZSM-5 based catalysts were tested for NOx reduction with C2H4 under oxidizing conditions in the temperature range between 250-600 deg C. Preliminary tests of the catalytic activity of the systems showed NOx reduction up to 95% at temperatures between 400-550 deg C using a mixture of a synthetic gas and air as reactant. 5 figs., 2 tabs., 8 refs.
