Methanol Dehydrogenation over Cu-containing Catalysts
https://doi.org/10.18412/1816-0387-2016-3-17-23
Abstract
Comparative studies of Cu-containing oxide catalysts with different chemical and phase compositions and thermodynamic analysis were aimed at identifying conditions for highly selective process of vapor-phase dehydrogenation of methanol to methyl formate or synthesis gas. It was shown that Cu0 nanoparticles formed during the reductive activation are differently selective to the formation of methyl formate from methanol and to its dehydrogenation to form synthesis gas. The proper choice of the catalyst composition and process conditions may provide a high selectivity (90–100 %) either to methyl formate or to synthesis gas. The catalysts based on the zincsilite type Cu-Zn hydroxosilicate and on CuAlZn aurichalcite are highly selective to methyl formate. The experimental data obtained with the most effective catalyst Cu/SiO2 for dehydrogenation to synthesis gas demonstrate that the yield of synthesis gas can reach 20 m3/h at the 1 atm pressure of methanol vapor, 200 °C and 0,5 s contact time.
