Abstract
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.
