基于详细机理动力学的研究成果 ,讨论了费 托合成单颗粒催化剂在液蜡填充情形下的详细模型化问题 ,建立了针对这一复杂多重反应体系的多组分扩散 反应的等温和非等温颗粒模型 .在此基础上 ,从催化剂设计灵活定位考虑 ,进一步建立了模型方程的有限元正交配置数值计算方法 . Based on the detailed mechanistic research results, the detailed model problems of Fischer-Tropsch single-particle catalyst in the case of liquid wax filling were discussed, and the isothermal and non-isothermal particles for multicomponent diffusion reaction of this complex multiple reaction system Model.On this basis, considering the flexible design of catalyst design, the numerical calculation method of finite element orthogonal configuration of the model equation is further established.
