Abstract

It is established that superactive catalysis of delignification oxidation processes could be realized thanks to activity intensification of variable valency metals, formation of additional number of labile active centers in lignin macromolecule, as well as transportation of electrons both inside polyconjugate system of lignin macromolecule and, possibly, through conductivity medium, alkaline solution being used for delignification. Five-stage reaction scheme is proposed according to which superactive catalysis of oxidative (oxygen) delignification of lignocellulose raw material is realized.
