SOLVOLYSIS PROCESS
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).

Process for the separation of levulinic acid from a biomass hydrolysate
The invention provides a process to separate levulinic acid from a biomass hydrolysate said process comprising extraction using as an organic solvent a substituted benzene comprising (i) at least one OR.sub.1 group wherein R.sub.1 is H or CH.sub.3; and (ii) at least one C.sub.1-3 alkyl group, wherein each of the at least one OR.sub.1 group is ortho positioned to at least one C.sub.1-3 alkyl group. Using said substituted benzene as extraction solvent gives good extraction efficiency, the extraction can advantageously be carried out at elevated temperature, and is very suitable for subsequent distillation steps.
