| Abstract: | 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 CHEMKIN software.The results showed that the temperature of 550-630K and the pressure of 1MPa are the most conducive to CO methanation. |
