Abstract:
The present report summarizes the results obtained during a systematic study of catalysts, their performances and fundamental principles of the preferential CO oxidation and preferential CO methanation reactions. CO PROX was studied over supported noble mono-metal based catalysts, supported bimetallic systems prepared with the use of double complex salts, and copper-ceria catalysts. CO MET was studied over nickel-based catalysts. The role of nickel precursor was investigated and the positive effect of chlorine on the catalyst selectivity was demonstrated. The catalysts were characterized by BET, XRD, XPS, TEM, EDX, TPR and TPD techniques.
Catalytic performance of the prepared systems in a form of grains in the fixed-bed continuous flow reactor was studied. The Cu/CeO2 catalysts were coated on the surface of microchanel reactors and investigated in CO PROX. The structured Ni/CeO2 catalysts supported over corrugated metal gauzes were studied in CO MET reaction in milli-channel reactor. The effect of internal diffusion was estimated and the optimum grain size/coating thickness was found.
