Uittreksel

The present invention relates to a process the production of a crude liquid lignin oil (CLO), said process comprises the steps of providing a lignin-rich solid feedstock and subjecting the lignin-rich solid feedstock to a treatment in a polar organic solvent in the absence of an effective amount of added reaction promoter, such as a heterogeneous and/or homogeneous catalyst and/or hydrogen, and providing a lignin composition, said treatment comprises a step of contacting said lignin-rich solid feedstock with a polar organic solvent under operating conditions of an operating temperature up to 210 °C, an operating pressure lower than 50 bar and a residence time up to 240 minutes, wherein the ratio (w/v) of lignin (in lignin- rich feedstock) to polar organic solvent ranges between 1:1.5 and 1:15, or between 1:2 and 1:10 or between 1:2 and 1:5.
