Title
Microkinetic modeling of Pt-catalyzed ethylene glycol steam reforming
Abstract

A predictive mean-field microkinetic model is developed for steam reforming of ethylene glycol over a Pt catalyst using a hierarchical multiscale modeling approach. The model's predictive capabilities are assessed by comparison to experimental data under kinetically controlled conditions. It is found that early dehydrogenation reaction steps control the reaction rate, highlighting a kinetic analogy between ethylene glycol steam reforming and CH4 steam reforming on Pt catalysts.
