Abstract

A catalytic process for generating at least one polyol from a feedstock comprising cellulose is performed in a continuous manner using a catalyst comprising nickel tungsten carbide. The process involves, contacting, continuously, hydrogen, water, and a feedstock comprising cellulose, with the catalyst to generate an effluent stream comprising at least one polyol and recovering the polyol from the effluent stream.
