对加压甲醇合成复合反应内扩散效率因子分别建立了一维多组分扩散模型、一维简化多组分扩散模型和一维关键组分扩散模型。用正交配置法求取数值解,并分别与对应的实验值比较,对各个模型的误差进行分析,提出了不同计算目的的适用模型。
A one-dimensional multi-component diffusion model, a one-dimensional simplified multicomponent diffusion model and a one-dimensional diffusion model of critical components were respectively established for the diffusion efficiency factors in the synthesis of pressurized methanol synthesis. The orthogonal solution method is used to solve the numerical solution. The experimental results are compared with those of the corresponding experimental data. The error of each model is analyzed and the applicable model for different calculation purposes is proposed.
