    摘要： The present invention relates to a method for producing lignin esterified with at least one fatty acid, wherein the method comprises the following steps: (i) reacting acetylated lignin with at least one fatty acid under the influence of heating and distilling at least part of the acetic acid formed during the reaction away from the reaction mixture, wherein per each mole of acetyl groups present in the lignin an excess molar amount of at least one fatty acid is used; and (ii) recovering lignin esterified with at least one fatty acid formed in step (i).

    摘要： The invention relates to a method for processing lignin. The method comprises: feeding lignin material (11) to the system, decreasing particle size of the lignin material (11) in a grinding device (30) in order to manufacture lignin powder having particle size distribution wherein at least 85 wt.% of the lignin agglomerates and particles are less than 300 microns, and increasing dry solids content of the lignin material at least 5 percentage units while decreasing the particle size in the grinding device (30). In addition, the invention relates to a system for processing lignin, a lignin powder, a method for manufacturing a product comprising lignin, a system for manufacturing a product comprising lignin and a product comprising lignin powder.
