Abstract
The present invention relates to a process for producing a lignin composition, which process comprises: - providing a lignin slurry comprising water and a water miscible organic solvent; - subjecting the lignin slurry to extraction at an extraction temperature of less than 100°C for an extraction time of at least 1 minute to provide an extracted slurry; - removing liquid from the extracted slurry to provide an extracted lignin; and - suspending the extracted lignin in a polar organic solvent to provide a lignin composition having a dry matter content of at least 30% by weight. The present invention also relates to a lignin composition comprising hardwood Kraft lignin and a polar organic solvent, which composition has a dry matter content of at least 30% by weight. The present invention also relates to use of the lignin composition as a fuel.
