Process for obtaining a stabilized lignin with a defined grain size distribution from a lignin-containing liquid

摘要

The invention relates to a process for obtaining a stabilized lignin having a defined particle size distribution from a lignin-containing liquid by adjusting the H + ion concentration of a lignin-containing liquid before and / or during a hydrothermal carbonization so that the desired particle size distribution of the hydrothermally carbonated lignin is obtained can be separated from the liquid containing the carbonated lignin and optionally purified.
