摘要
探讨了合成气甲烷化过程中各反应的热力学平衡常数与温度的关系,并使用CHEMKIN软件计算了反应温度、压力对CO转化率、CO2和甲烷选择性和收率的影响。结果表明:温度在550K^630K之间,压力为1MPa,是甲烷化反应的优化条件。
The relationship between thermodynamic equilibrium constant and reaction temperature for various reactions in syngas methanation were calculated and discussed. The influences of temperature and pressure on CO conversion, CH4 selectivity and yield were simulated thermodynamically using the CHEMK/N software. The results showed that the temperature of 550-630K and the pressure of 1MPa are the most conducive to CO methanation.
