Catalytic Process for the Production of Alcohols from Biomass-related Feedstock

The present invention pertains generally to a catalytic technology for converting biomass- related feedstock into useful or value-added chemicals. More specifically, this invention relates to a catalytic process for the production of lower alcohols, and preferably for the production of C4 to C6 polyols from polysaccharides with ss-glycoside linkages. A particular aspect of the present invention relates to a single-step catalytic process, using a heterogeneous catalyst, to produce C4 to C6 polyols such as sorbitol, mannitol, xylitol and erythritol, mixtures thereof and their partially dehydrated and/or dehydrogenated products such as sorbitan, isosorbide and sorbose from polysaccharides containing ss-glycoside functionalities such as in cellulose, chitin and particular bacterial biopolymers. The heterogeneous catalyst which comprises non-noble transition metal(s) and acid carrier(s) is characterized by thermal pretreatment in a carbon-containing atmosphere in order to obtain increased sugar alcohol yields.
