Tri-Reforming Process for Conversion of Hydrocarbons to Hydrogen

Abstract

The process of methane tri-reforming can effectively produce hydrogen and synthesis gas with an adjustable H2/CO molar ratio under minimal environmental impact and optimal energy consumption. This is achieved through a combination of carbon dioxide reforming, steam reforming, and partial oxidation of methane in a single reactor. The process is thoroughly evaluated in this work, including the reactions and their kinetics, the impact of operating conditions on CO2 and CH4 conversion and hydrogen production, and the use of practical catalysts. Different reactor configurations are also compared. Despite the progress made, methane tri-reforming still faces technical challenges and appears to be in its early stages of development. © 2025 selection and editorial matter, Mohammad Reza Rahimpour, Mohammad Amin Makarem and Parvin Kiani.
