Abstract: A process for 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 less than wt. % water, is separated into a pre-treated solid residue comprising cellulose and a liquid stream comprising dissolved lignin. 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 part of the liquid stream is separated to produce a second portion of organic solvent and a lignin stream. At least part of the first and second portions of organic solvent is recycled to the contacting step.

Abstract: The invention provides a process for the separation of a first C3 to C7 diol from a first mixture of C3 to C7 diols. The first mixture is provided to a first distillation column. An extractant is fed to the first distillation column above the first mixture. A stream comprising the first diol and the extractant is removed as a bottoms stream from the first distillation column and subjected to distillation in a second distillation column. A high purity first diol stream is removed from the top section of the second distillation column, while a used extractant stream is removed from the bottom section. The extractant is a C3 to C6 sugar alcohol or mixture thereof. The first diol is a close-boiler to and/or forms an azeotrope with one or more of the other C3 to C7 diols present in the first mixture.
