Hydrogen production by steam-reforming of methanol: Transfer intensification
The aim of this numerical work is to study the influence of flow turbulence (offset OSF fins coated with CuO/ZnO/Al2O3 catalyst) on the conversion rate of methanol and also on the selectivity of this catalytic reaction. A thorough literature search of methanol steam reforming permitted retaining for this work the kinetic model developed by Peppley (1997) based on the SRM, WGS and methanol decomposition equations. A one-dimensional reactor approach allowed validating the kinetic model using the experimental results from literature for different operational conditions. A sensitivity study to the significant parameter of the process (temperature, pressure, H2O/CH3OH ratio, etc.) is then carried out. A two-dimensional approach revealed the influence of reactor geometry and catalyst as well as the existence of certain regions in the reactor which favour certain reactions (sometimes coupled) in steam reforming of methanol. Finally the effects of turbulence generators on the conversion rate of methanol and the selectivity of the catalytic reaction was investigated. Two aspects were specifically studied: “flow” and “reactive surface distribution”. A reactor composed of catalyst coated inserts (offset fins) is compared with a duct flow, and promising numerical results are obtained.
Keywords: Steam reforming of methanol, hydrogen production, Transfer intensification, multifunctional heat exchanger.
