Abstract
A method of treating lignin-based material is provided, comprising the steps of subjecting lignin separated from lingo-cellulosic raw material to hydrothermal carbonization process at an elevated temperature, where carbonized lignin having increased carbon content is obtained, and stabilizing the obtained carbonized lignin under inert atmosphere at a stabilization temperature higher than the temperature of the hydrothermal carbonization process.
