Abstract: | Steam reforming of methanol, CH3OH + H2O 3H2 + CO2, was carried out over various Pd catalysts (Pd/SiO2, Pd/Al2O3, Pd/La2O3, Pd/Nb2O5, Pd/Nd2O3, Pd/ZrO2, Pd/ZnO and unsupported Pd). The reaction was greatly affected by the kind of support. The selectivity for the steam reforming was anomalously high over Pd/ZnO catalysts. |
