A detailed surface reaction model for syngas production from butane over Rhodium catalyst

Journal Article (Journal Article)

This paper presents numerical and experimental investigations of syngas production from butane. A surface reaction mechanism is used to model the reaction pathways. The butane reforming simulations and experiments are conducted in two reformers (tubular and radial). Starting from the reaction mechanism for methane conversion over a Rh catalyst, a reaction mechanism for butane conversion over the same catalyst is developed. The surface reaction equations are coupled with the flow equations. Porous resistance, catalyst concentration and reaction rate constants of the introduced reaction pathways are estimated by comparing the results of the model with the experimental data. The model is able to capture the main features of the species profiles along the reactors as well as the selectivity trends for different equivalence ratios. Moreover, the model predicts the fractional coverage of the surface species and therefore provides an insight into the reaction mechanisms on the catalyst surface. © 2011, Hydrogen Energy Publications, LLC.
