“…POX has been identified as the ideal reaction path for hydrocarbon processing to syngas and investigated experimentally and numerically for different hydrocarbon fuels, e.g., methane (Neumann and Veser, 2005;Stutz et al, 2006;Stutz and Poulikakos, 2005) and higher alkanes (Panuccio et al, 2006;Williams and Schmidt, 2006). Another effective reaction for hydrocarbon processing is steam reforming (SR), where butane reacts with water:…”

“…114 Wall conduction is also an important parameter and hydrogen yield is observed to be the highest for no or very low conductive walls. 123 Stutz et al 124 numerically investigated the effect of catalyst surface site density and reactor geometry on the performance of a single-channel microreactor. An important conclusion derived from their study was that hydrogen selectivity is dependent on the catalyst loading which is an important degree of freedom to maximize H 2 productivity.…”

Process intensification aspects for steam methane reforming: An overview

2009

Steam methane reforming (SMR) is the most widely used process in industry for the production of hydrogen, which is considered as the future generation energy carrier. Having been perceived as an important source of H2, there are abundant incentives for design and development of SMR processes mainly through the consideration of process intensification and multiscale modeling; two areas which are considered as the main focus of the future generation chemical engineering to meet the global energy challenges. This article presents a comprehensive overview of the process integration aspects for SMR, especially the potential for multiscale modeling in this area. The intensification for SMR is achieved by coupling with adsorption and membrane separation technologies, etc., and using the concept of multifunctional reactors and catalysts to overcome the mass transfer, heat transfer, and thermodynamic limitations. In this article, the focus of existing and future research on these emerging areas has been drawn. © 2009 American Institute of Chemical Engineers AIChE J, 2009

“…Numerical calculations for the POM in a single microchannel of 10 mm in length and 1 mm in diameter, used as a model of an adiabatic ceramic monolith, showed that at the feed temperature 580°C, a hot zone with the temperature ranging from 830°C to 930°C was formed at a 1-mm distance from the reactor inlet. The oxygen was almost completely consumed within the first 2 mm of the channel [9].…”
