Investigation of thermal degradation of hydrolysis lignin

Abstract

Wood hydrolysis facilities were built in both northern and southern European regions of Russia, as well as in Siberia and the Russian Far East. Other hydrolysis plant in the former USSR were located in Ukraine, Belarus, Uzbekistan, Kazakhstan, Moldova and Lithuania. All or most of these facilities produced substantial amounts of excess lignin, so called "hydrolysis lignin" (HL). Technology of energy utilization of HL, having a great potential is a production of granulated fuel. Perspective way is pelletization of HL. In this paper complex kinetic analysis of hydrolysis lignin and its organic components under conditions of dynamic and isothermal heating was carried out. Kinetic parameters are determined using the extended independent parallel model.
