Özet
Catalytic conversions of methanol, ethanol, and propane in two parallel microchannels, repeating unit of a multichannel reactor involving successive exothermic combustion and endothermic reforming channels, are simulated to investigate the effect of design parameters on hydrogen yield. Simulations conducted using computational fluid dynamics (CFD) at steady-state show that parameters such as distance between and dimensions of the microchannels and use of micro-baffles within the channels affect heat transfer to the reforming zone and hydrogen yield. Dynamics of the microchannel conversion are also investigated by transient CFD simulations. © 2009 Springer Science+Business Media, LLC.
