| titleOfInvention | Pre-treatment of lignocellulosic feeds for the production of glycols |
| abstract | A process for the preparation of glycols from a lignocellulosic solid biomass comprising cellulose, hemicellulose and lignin in a reactor system, said process including: a) contacting the lignocellulosic solid biomass with an organic solvent comprising a low boiling point alcohol and a pre-treatment acid at a temperature ranging from about 80 to about 220°C and a pressure ranging from 1 to 50 bar (absolute) for a time ranging from about 5 minutes to about 2 hours to obtain a first mixture; b) separating the first mixture obtained in step (a) into a pre-treated solid residue comprising cellulose and a liquid stream comprising dissolved lignin and hemicellulose; c) subjecting the pre- treated solid residue to a hydrogenolysis reaction and generating a glycols stream, a lights stream and a heavies stream; d) recycling at least a part of the lights stream to step (a), wherein the lights stream comprises a first portion of the organic solvent; e) separating at least of part of the liquid stream from step b) to produce a second portion of the organic solvent and a solid residue that comprises lignin and hemicellulose; and f) recycling at least a part of the second portion of the organic to step (a), wherein the first mixture has greater than about 20 wt% water. |
