The kinetic study of abies wood delignification by H2O2 in the medium acetic acid – water was firstly studied in the presence of TiO2 catalyst under mild conditions: temperatures 70 – 100 °C, atmospheric pressure. The oxidative delignification process is described satisfactory by the first order equation in all temperature range. The rate constants are varied between 0.80– 12.3 10-3min-1 and the activation energy is near 81 kJ•mol-1. The optimal parameters of delignification process, providing the effective fractionation of abies wood on microcrystalline cellulose and soluble lignin, were established by experimental and numerical methods.
