A novel kinetic model for liquid-phase selective oxidation of glycerol over Au-supported catalysts, involving the reactions in the bulk liquid phase, the formation of reactive oxygen species on Au metal and support, and three reactions of different oxygen species, was developed. The innovations of this model are that the catalyst has two types of active sites, definition of the coverage of active sites on the Au (as α), and the consideration of the different active species involved in each reaction. This approach enabled optimization of the reaction conditions and highlighted aspects of the catalyst design to maximize the target product yield. The model is highly versatile and successfully predicts the oxidation behavior under a wide range of conditions. It also predicted the experimental results reported by other researchers. Therefore, the model is expected to be a useful tool for catalyst design and prediction of reaction conditions in liquid-phase biomass conversion.

“…Some studies have reported the activation of alcohols by a base. Kishida et al (2006) and Fukumura et al (2016) have demonstrated kinetically that the first step of the glycerol hydrothermal reaction in the presence of a homogeneous base is the formation of a glycerol alkoxide, 2,3‐dihydroxypropoxide C 3 H 7 O 3 − , through interaction between glycerol and the base. Zope et al (2010) performed calculations based on density function theory (DFT) for the oxidation of ethanol to acetic acid over an Au catalyst under basic conditions.…”

Glycerol can be effectively converted to glyceric acid, a high value‐added pharmaceutical raw material, through its partial oxidation over an Au/Al2O3 catalyst under strongly basic conditions. The factors important for the highly selective production of glyceric acid were investigated experimentally. It was clarified that NaOH was involved in the glycerol activation step to a glycerol alkoxide intermediate (2, 3‐dihydroxypropoxide) in the liquid phase, then glyceric acid was formed by OOH species derived from O2 on an Au catalyst in the partial oxidation step. We have newly discovered the concerted effect of NaOH and O2 in different reaction steps.
