Key words: delignification, supercritical fluids, lignin, hydrogen peroxide, oxidation
Advantages of the low-temperature wood oxidative delignification are reviewed. Main
applications of the supercritical CO2 to the wood chemical technology are listed. Data
on the influence of the pressure upon the oxidation of the wood substance by hydrogen
peroxide in the supercritical carbon dioxide medium is obtained. Prospects of the
application of hydrogen peroxide jointly with the supercritical CO2 to wood
delignification process are revealed.
