The present invention is directed to a process for the production of thermally stabilized agglomerated lignin, which avoids melting and/or significant foaming during subsequent thermal processing. The process comprises the steps of providing agglomerated lignin and heating the agglomerated lignin to obtain thermally stabilized agglomerated lignin. The thermally stabilized lignin can be further processed to a carbon enriched material.
