本文采用正交配置法求解耐硫甲烷化催化剂的二维反应传质传热模型。模型计算值与实验测试值较为吻合。模拟结果表明：由于甲烷化反应与变换反应交互作用，ζＣＨ４较大，ζＣＯ２很小；催化剂粒内温差较小，颗粒可视为等温；粒内浓差明显。
In this paper, orthogonal configuration method is used to solve the two-dimensional mass transfer heat transfer model of sulfur-tolerant methanation catalyst. The calculated values are in good agreement with the experimental values. The simulation results show that the ζCH4 is larger and the ζCO2 is smaller due to the interaction between the methanation reaction and the shift reaction. The intraparticle temperature difference is small and the particles can be considered isothermal. The intragranular concentration is obvious.
