摘要：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。
The twodimensional model of reactionmass transferheat transfer for sulfurtolerant methanation catalyst has been solved by orthogonal collocation method The simulation data of the model are in good agreement with the experimental results ζ CH 4 is larger and ζ CO 2 is very small because of the interaction between methanation and shift reaction Temperature difference within the pellet is smaller, which shows that the pellet is close to isothermal, while concentration difference is larger
