Abstract
The catalytic decomposition of methanol on the Group VIII metal catalysts was studied using a conventional flow reactor. From the comparison of activity and selectivity for 2H2+CO formation, Ni was found to be a suitable main catalyst component. The partial pressure dependence of the decomposition rate showed that methanol was strongly adsorbed on the catalyst surface at higher pressures, resulting in substantial retardation. However, it decreased with increasing temperature. For this reason, Ni catalysts showed a considerable range of change in the rate at 350°C, while a three-component catalyst, Ni-La2O3-Ru, exhibited stable activity during the reaction, and it is suitable catalyst for synthesis-gas formation.
