Abstract:
1. A process for generating at least one polyol from a feedstock comprising cellulose, the process comprising: a) contacting, in a continuous manner, in a reaction zone, hydrogen, water, and a feedstock comprising cellulose, with a catalyst system comprising an unsupported component comprising a compound selected from the group consisting of a tungsten compound, a molybdenum compound, and any combination thereof, and a supported component comprising a supported active metal component selected from the group consisting of Pt, Pd, Ru, Rh, Ni, Ir, and combinations thereof on a solid catalyst support, to generate an effluent stream comprising at least one polyol; b) separating hydrogen from the effluent stream and recycling at least a portion of the separated hydrogen to the reaction zone; c) separating water from the effluent stream and recycling at least a portion of the separated water to the reaction zone; and d) recovering the polyol from the effluent stream.
