The aim of this work was to study the influence of the modification of montmorillonites by carbonaceous and Al species as well as copper deposition. Commercial acid-treated montmorillonites, K5 and K30 (Sigma-Aldrich GmBH), were modified and used as catalysts in Selective Catalytic Reduction process of nitrogen oxides by ammonia. The characterisation was carried out by low-temperature nitrogen sorption, Fourier-transform-infrared spectroscopy and X-ray diffraction. Catalytic performance in SCR-NH3 of so-modified montmorillonites was compared under the following conditions: mass of catalyst: 200 g, flow 100 cm3/min, reaction mixture: 800 ppm NO, 800 ppm NH3, 3 % O2, and He. The modification with copper and polyacrylamide led to the increase in NO conversion. The studied catalysts showed low N2O formation.
