Abstract
According to X-ray phase and spectral analyses, the NTK-10-1 catalyst is a mixture of ZnO, CuO, NiO, ZnAl2O4, CuAl2O4, and CaCO3. Under conditions of selective reduction of nitrogen oxides by propane, nitrite and nitrate complexes are formed on the surface of the NTK-10-1 catalyst. With an increase in temperature, nitrite complexes transform to nitrate complexes at a rate that decreases in the presence of propane in the gas phase. Propane adsorption is an activated process in which oxygen plays an important role. The results of temperature-programmed reduction showed that oxygen readily desorbs from the catalyst surface even under oxidative conditions.
