Abstract
A catalytic process for generating at least one polyol from a feedstock comprising cellulose is performed in a continuous manner. The process involves, contacting, continuously, hydrogen, water, and a feedstock comprising cellulose, with a catalyst to generate an effluent stream comprising at least one polyol, water, hydrogen, and at least one co-product. The water, hydrogen, and at least one co-product are separated from the effluent stream and recycled to the reaction zone. The polyol is recovered from the effluent stream.
