二氧化碳加氢合成甲酸的热力学分析

Thermodynamic Analysis of CO_2 Hydrogenation to Formic Acid

用热力学的方法分析了二氧化碳加氢合成甲酸的反应.计算了温度、压力对反应的平衡转化率的影响,表明CO2的平衡转化率随着反应温度、压力的增大而增大.但即便在高压和较高的温度下,也很难实现CO2加H2向甲酸的高效转化.

The reaction of CO2 hydrogenation to formic acid has been analysed using thermodynamic method,and the influence of reaction temperature and pressure also has been studied. It indicates that the CO2 equilibrium conversion increases along with the increase of temperature and pressure. But even though the reaction occurs under high pressure and high temperature, it is difficult to realize the efficient synthesis of formic acid by CO2 hydrogenation.
