•An innovative reactor was designed to measure hydrothermal reaction kinetics.•At temperatures between 200 and 260°C, weight loss kinetics are quite rapid.•Reactions are modeled by parallel first-order degradation of hemicellulose and cellulose.•Mass transfer and reaction kinetics may both be import...
