摘要
A process for recovering carbonized lignin having a defined grain size distribution from a lignin-containing liquid is provided. The lignin-containing liquid is subjected to a hydrothermal carbonization to convert the lignin into a carbonized lignin and the carbonized lignin is separated from the liquid containing the carbonized lignin. The lignin-containing liquid is subjected to a hydrothermal carbonization at temperatures in the range from about 150° C. to about 280° C. and by adapting the H+ ion concentration in the lignin-containing liquid before and/or during the hydrothermal carbonization the grain size distribution of the carbonized lignin is adjusted.
