Abstract: The present disclosure relates to the thermal liquefaction of lignin, and more particularly to lignin solvolysis of a lignin feedstock (10) or a lignin-based feedstock (10). The process comprises subjecting a feed mixture (30) of lignin feedstock (10) or lignin-based feedstock (10) and solvent (20) to a thermal liquefaction step by heating (110) the feed mixture (30) at a temperature between 300 and 420° C. and at a pressure below 35 bar, wherein the solvent (20) of the feed mixture (30) is a recycled product fraction (61) separated (120) from the obtained liquid product mix (50). The present disclosure further relates to the use of the obtained product(s).
