A series of CuCoCe/CNTs catalysts with different Cu/Co mass ratio were prepared by co-impregnation method to study the influence of the adjustment of Cu/Co mass ratio on the catalystic performance of the catalysts for higher alcohols synthesis from syngas. The catalyst showed highest space-time yield (783.72 mg · g-1 · h-1) and selectivity of higher alcohols (42.46%) while the selectivity of methanol in alcohol distribution was only 17.29%when the mass ratio of Cu/Co was 2.Our research results show that the catalyst with Cu/Co was ratio 2 had better crystal structure and dispersion of active metal particles and oxidation-reduction ability. Meantime, the carbon nanotube support had excellent confinement effect. All these characteristic made the catalytic activity improved significantly. |
