摘要
The selective hydrogenation of carbon dioxide to methanol by the low pressure process was investigated over a Cu/Zn/Al catalyst in a stirred reactor. Two different reaction domains were defined as a function of the contact time. The selectivity for methanol increases when the contact time decreases. Correlatively, Cu//2O was observed in the catalysts of higher selectivity and electron probe micro-analysis showed a higher dispersion of the elements compared with the dispersion of samples treated with the highest contact times.
