摘要：
Disclosed is a process for preparing ethylene glycol from polyhydric compounds, including cellulose, starch, hemicellulose, sucrose, glucose, fructose, fructosan, xylose and soluble xylo-oligosaccharide. In the present process, the polyhydric compounds are used as the starting materials, and a composite catalyst is composed of the following active catalytic components: transitional metals of iron, cobalt, nickel, ruthenium, rhodium, palladium, iridium, platinum of Groups 8, 9, 10, and also oxide of tungsten, sulfide of tungsten, chloride of tungsten, hydroxide of tungsten, tungsten bronze, tungstenic acid, tungstate, metatungstic acid, metatungstate, paratungstic acid, paratungstate, peroxytungstic acid, peroxytungstate and heteropoly acid of tungsten. Ethylene glycol is produced through catalytic conversion in one step under hydrothermal conditions at 120-300ºC and hydrogen pressure of 1-13 MPa.
