Abstract Tri-reforming process of methane has been considered as an important chemical process for syngas production. The aim of this study is modeling and optimization of methane Tri-reforming slurry bubble column reactor (SBCR). A one-dimensional heterogeneous model with plug flow pattern for gas phase and an axial dispersion pattern for liquid-solid suspension has been developed for modeling of SBCR. differential evolution (DE) approach has been used for the optimization of Tri-reforming slurry reactor operating conditions. The effect of operating parameters such as inlet temperature, the ratios of O2/CH4, H2O/CH4, and CO2/CH4 on the temperature of gas, methane conversion, hydrogen production, and H2/Co ratio in the output of reactor are investigated. Methane conversion, hydrogen yield, and H2/Co ratio in optimization conditions were obtained 92%, 1.81, and 1.76, respectively. The results suggest that employment this type of reactor could be feasible and beneficial.

差分演化优化法模拟甲烷三重整浆泡塔反应器生产合成气

摘要 甲烷三重重整工艺被认为是生产合成气的重要化学工艺。本研究的目的是模拟和优化甲烷三重整浆液泡罩塔反应器 (SBCR)。已经开发了一种一维非均相模型，该模型具有气相的活塞流模式和液固悬浮的轴向分散模式，用于模拟 SBCR。差分演化（DE）方法已被用于优化三重整浆反应器的操作条件。研究了入口温度、O2/CH4、H2O/CH4和CO2/CH4比等操作参数对反应器输出气体温度、甲烷转化率、氢气产量和H2/Co比的影响。甲烷转化率、氢气收率、优化条件下的 H2/Co 比分别为 92%、1.81 和 1.76。结果表明，使用这种类型的反应器可能是可行和有益的。
