Abstract: A process for the preparing glycols from a lignocellulosic solid biomass involves contacting the biomass with an organic solvent comprising a low boiling point alcohol and a pre-treatment acid at a temperature in a range from 80 to 220° C. and a pressure in a range from 1 to 50 bara. The resulting mixture, having >20 wt. % water, is separated into a pre-treated solid residue comprising cellulose and a liquid stream comprising dissolved lignin and hemicellulose. The pre-treated solid residue is subjected to a hydrogenolysis reaction, generating a glycols stream, a lights stream, comprising a first portion of organic solvent, and a heavies stream. At least of part of the liquid stream is separated to produce a second portion of organic solvent and a solid residue of lignin and hemicellulose. At least part of the first and second portion of organic solvent is recycled to the contacting step.
