Hydrogen production by methanol steam reforming in an annular microchannel on a Cu-ZnO catalyst

Steam reforming of methanol into a hydrogen-containing gas under activated methanol conversion on annular microchannel walls was experimentally investigated. The methanol conversion was carried out on a copper-zinc catalyst deposited on the channel internal wall. The concentrations of the chemical conversion products in the output gas mixture were determined at different reactor temperatures and residence times. The channel wall temperature range within which the methanol steam reforming is intensified was also determined. It was shown that the CO content in the reaction products is determined by the CO 2 partial pressure rather than by the reactor temperature. A kinetic model of methanol steam reforming on a copper-zinc catalyst was developed.
