Cu/Co比调变对合成气制低碳醇CuCoCe催化剂性能的影响
Adjustment of the Mass Ratio of Cu/Co and Its Effect on the Performance of CuCoCe Catalyst for Higher Alcohol Synthesis from Syngas
摘要
Abstract
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 wass 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.关键词
