An extensive review of slurry bubble column reactor and fixed bed reactor steady state models for Fischer–Tropsch synthesis is presented in this work. Material, energy and momentum balance equations are presented here along with the relevant findings of each study for modelling purposes. For fixed bed reactor models, one-dimensional and two-dimensional models can be differentiated, with the latter being better at predicting hot spots and thermal runaways, although the computational effort required solving them is also higher. Fixed bed reactors can also be classified as pseudo-homogeneous or heterogeneous models, the former considering that all phases are in thermal and chemical equilibrium, and the latter having different profiles for the catalyst particles, generally including a pellet model. For slurry bubble column reactors, single-class and double-class bubble models can be differentiated. The double-class bubble models represent better churn-turbulent regimes at the expense of a higher computational effort.

费-托合成固定床和浆液泡罩塔反应器的建模

本文对费-托合成的浆液泡罩塔反应器和固定床反应器稳态模型进行了广泛的回顾。此处介绍了材料、能量和动量平衡方程以及用于建模目的的每项研究的相关发现。对于固定床反应器模型，可以区分一维和二维模型，后者更擅长预测热点和热失控，尽管解决它们所需的计算量也更高。固定床反应器也可以分为伪均相或非均相模型，前者考虑到所有相都处于热平衡和化学平衡，而后者具有不同的催化剂颗粒分布，通常包括颗粒模型。对于浆液泡罩塔反应器，可以区分单类和双类泡沫模型。双级气泡模型以更高的计算量为代价代表了更好的搅动-湍流状态。
