Abstract
The kinetics of methanol dehydrogenation over carbon-supported copper catalyst was studied. The catalyst was prepared by the incipient wetness impregnation of carbonaceous graphite-like material Sibunit with aqueous solution of copper nitrate. The resulting Cu/C samples were calcined and reduced in a hydrogen flow within temperature interval of 200–400 °C. Experiments were carried out in a flow-through fixed-bed tubular reactor. Observable rate constants were determined for the reactions of methanol dehydrogenation to methyl formate and methyl formate decomposition on carbon monoxide and hydrogen. The process of methanol dehydrogenation in a tubular reactor was simulated by means of mathematical modeling. The estimation of kinetic parameters in accordance with experimental data obtained for the Cu/C sample reduced at 300 °C has allowed us to consider the reversibility of methanol dehydrogenation reaction.
