A thermodynamic view of partial oxidation, steam, reforming, and autothermal reforming on methane

Thermodynamic analysis on three thermo-chemical reforming processes, i.e., partial oxidation (POX), steam reforming (STR), and autothermal reforming (ATR) with methane as the feedstock fuel are conducted in this study. The focus of this article is to show the effect of air-fuel (AF) ratio, water-fuel (WF) ratio, temperature and pressure on hydrogen (112) yield, hydrogen/carbon monoxide (H-2/CO) ratio, carbon (C), and carbon monoxide (CO) formation. Optimal operating conditions under no solid carbon formation in the reaction are recommended for each thermochemical reforming technique.
