摘要:
采用金属 Al 为还原剂,金属 Ni 和 Cu 为催化剂,研究了水热条件下 CO2 催化转化生成甲酸的特性.针 对水热还原 CO2 可能存在的 4 个反应途径进行热力学分析,计算表明,水热条件下反应途径 HCO3-+ 2H  HCOO-+H2O 在热力学上最易进行,还原氢的最佳存在形态为活性 H 原子.考察了铝镍和铝铜水热反应 体系中 Ni/Al 摩尔比、Cu/Al 摩尔比、Al/C 摩尔比、反应时间和温度等对产物甲酸浓度和碳转化率的影响,实验 表明,Cu 催化剂水热转化 CO2 生成甲酸的碳转化率优于 Ni 催化剂,当 Al/Cu/NaHCO3 的 3 组分摩尔比为 8∶8∶ 1、温度 300,℃、反应 120,min 时,水热还原 CO2 生成甲酸的碳转化率为 29.1%,.
Abstract:
Catalytic reduction of CO2 into formic acid was investigated through hydrothermal reactions with Al as reducer and Ni/Cu as catalysts.A thermodynamic analysis was carried out to evaluate four potential reaction pathways of CO2 hydrothermal reduction.It was found that the most feasible pathway was as follows:HCO3-+ 2,H  HCOO-+H2O,and active H atom was the best existence state of reduced hydrogen.The influences on formic acid product and carbon conversion efficiency of molar ratios of Ni/Al,Cu/Al and Al/C,reaction time and temperature were investigated in Al-Ni and Al-Cu reaction systems.It was proved experimentally that the carbon conversion efficiency during CO2 reduction into formic acid with Cu catalyst was higher than that with Ni catalyst.The carbon conversion efficiency was 29.1%, during CO2 reduction into formic acid at 300,℃ for 120 min when the molar ratio of Al/Cu/NaHCO3 was 8∶8∶1.
