以化学热力学为基础，利用FactSage软件对2种典型的煤气化合成气甲烷化反应过程进行了热力学计算和分析。研究了合成气的组分、氢气的配比、反应温度、压力等条件对甲烷化过程的影响，特别是氢气的配比研究，区别于常规对H2/CO分析而是以氢气的理论配比 H2/(3CO+4CO2)进行分析。结果表明：反应器操作压力对甲烷化过程的影响不明显，合成气的组分、氢气的配比、反应温度的选择对甲烷化过程的影响较大。得出：合成气甲烷化过程应采用多段反应器，最终控制温度为(300~350)℃；操作压力一般为(3.0~3.5) MPa；H2的配比采用理论配比时生产出的CH4浓度高。

Based on the chemical thermodynamics, thermodynamic calculations and analysis of the two typical gasification syngas methanation process using the software of FactSage. Researching the effects of components of synthesis gas, hydrogen ratio, reaction temperature and pressure conditions on the methanation process, especially the ratio of hydrogen research which is different from conventional analysis of the H2/CO ratio, but for the theoretical hydrogen H2/(3CO+4CO2). The results showed that: the process operating pressure implies the methanation reaction is not significant, and the composition, the ratio of hydrogen, the reaction temperature implie the synthesis gas methanation process are signficant. Multi-stage reactor with the temperature of (300 ~ 350)℃, operating pressure of (3.0 ~ 3.5) Mpa, and the theoretical H2 ratio should be used in synthesis gas methanation process for high concentrations of CH4.
