Comment on: “CFD modeling of hydrogen production using steam reforming of methane in monolith reactors: Surface or volume-base reaction model?” by Mohammad Irani et al., Int J Hydrogen Energy 2011,36:15602–15610

Abstract

In this comment we point out the impact of the high specific surface area of the washcoat should not be neglected when the volumetric approach is employed to simulate the catalytic reaction. We recommend that the authors use a new value of Pwashcoat to improve the simulation accuracy of volumetric approach which probably gives much more reliable results.
