摘要

Catalytic dehydrogenation of methanol to methyl formate over SiO2-, hydroxyapatite (HAP)-, and MgO-supported copper catalysts was investigated. Metallic copper (Cu-0) was the active site for the methanol dehydrogenation to methyl formate. Cu/SiO2 catalyst with low basicity and weak-strength basic site effectively catalyzed the methanol dehydrogenation to methyl formate. Cu/HAP and Cu/MgO catalysts with high basicities and strong-strength basic sites caused the degradation of the resultant methyl formate to CO and H-2. Over Cu(5)/SiO2 catalyst, the reaction activation energies for methanol dehydrogenation to methyl formate and methyl formate degradation to CO and H-2 were 58.3 and 91.1 kJ mol(-1), respectively.
