The function of Lewis and Brønsted acid sites has been established in reference to the kinetic model that we developed for xylose dehydration. Lewis sites decrease furfural selectivity by catalyzing the reaction between xylose and furfural to form humins. Likewise, catalyst pore confinement has an adverse effect on furfural selectivity.
