Microkinetic modeling of Pt-catalyzed ethylene glycol steam reforming

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.

► A predictive mean-field microkinetic model is developed for steam reforming of ethylene glycol on a Pt catalyst.
► Early dehydrogenation reactions control the reaction rate and OH-assisted reactions do not contribute to the overall rate.
► Steam reforming of ethylene glycol is the superposition of catalytic pyrolysis and water–gas shift reactions.
► The results highlight a kinetic analogy between CH4 steam reforming and ethylene glycol steam reforming over Pt catalysts.
