Zusammenfassung:Methods and apparatuses for catalytically generating a polyol from biomass are provided. An exemplary method includes the steps of: contacting a feed stream comprising biomass to acid conditions in a first reaction zone, wherein the acid conditions in the first reaction zone are sufficient to hydrolyze a saccharide from the biomass to generate glucose; directing at least a first portion of a first effluent from the first reaction zone to a second reaction zone; and contacting the at least first portion of the first effluent with a first saccharide-to-polyol catalyst system under conditions suitable for catalytic conversion of saccharide to polyol.
