Comparing the Polyoxometalate-Catalyzed Oxidation of C5-Containing Biomass to Formic Acid in a Taylor-Flow Microreactor and a Stirred-Tank Reactor.

ABSTRACT: Biomass valorization using polyoxometalate-based (POM) catalysts is a promising strategy for green and sustainable chemistry. In the modified OxFA process, various biogenic substrates can be selectively oxidized to the sustainable hydrogen carrier formic acid using the H₈PV₅Mo₇O₄₀ (HPA-5) POM catalyst in an aqueous-methanolic solution with molecular oxygen or compressed air as an oxidant. A current challenge of the mainly used stirred-tank reactors is the mass transfer limitation with respect to the effective dissolution of oxygen in the reaction media. In order to improve gas-liquid mass transfer, alternative reactor concepts are needed. Herein, we demonstrate the selective catalytic oxidation of the C5 model sugar xylose as well as the commerci
