A statistical modeling and optimization study on the thermodynamic equilibrium ofmethanol steam reforming (MSR) process was performed by using Aspen Plus and theresponse surface methodology (RSM). The impacts of operation parameters; temperature,pressure and steam-to-methanol ratio (H2O/MeOH) on the product distribution wereinvestigated. Equilibrium compositions of the H2-rich stream and the favorable conditionswithin the operating range of interest (temperature: 25e600 C, pressure: 1e3.0 atm, H2O/MeOH: 0e7.0) were analyzed. Furthermore, ideal conditions were determined to maximizethe methanol conversion, hydrogen production with high yield and to minimize the undesirable products such as CO, methane, and carbon. The optimum corresponding MSRthermodynamic process parameters which are temperature, pressure and H2O/MeOH ratiofor the production of HT-PEMFC grade hydrogen were identified to be 246 C, 1 atm and 5.6,respectively.
