Influence of Two-Dimensional Distribution Schemes upon Reactor Performance in a Ceramic Microchannel Network for Autothermal Methanol Reforming Conference Paper uri icon

abstract

  • In this work, the authors design, fabricate, and evaluate three prototype ceramic microchannel reactor architectures with two-dimensional complex flow configurations for coupling methanol steam reforming with methanol combustion/partial oxidation. These prototypes were evaluated for the autothermal hydrogen production from methanol in order to investigate the influence of individual process flow rates and radial distribution schemes upon thermal gradients and overall system performance in the absence of any external insulation. Results demonstrate that, in the case of low thermal conductivity ceramic substrates, appropriate selection of two-dimensional radial distribution patterns enables the tailoring of one- and three-dimensional thermal gradients for enhancing self-insulating qualities of the microchannel reactor as well as enhancing overall hydrogen yields. © 2010 American Chemical Society.
