Abstract:
The invention provides a process for the selective hydrogenation of glycolaldehyde in a process stream comprising glycolaldehyde and one or more monosaccharide in a solvent, said process comprising contacting the process stream with hydrogen in the presence of a hydrogenation catalyst composition at a temperature of no more than 150° C. and for a residence time of no more than 90 minutes.

Claim (Index 3):
A continuous process for the preparation of monoethylene glycol from starting material comprising one or more saccharides by:\n i) contacting a feed stream comprising said starting material in a solvent with a retro-aldol catalyst composition in a first reaction zone at a temperature in the range of from 160 to 270\u00b0 C. to provide an intermediate process stream comprising one or more monosaccharide and glycolaldehyde; ii) then contacting said intermediate process stream with hydrogen in the presence of a hydrogenation catalyst composition in a second reaction zone at a temperature of no more than 150\u00b0 C. and for a residence time of no more than 90 minutes; iii) withdrawing a product stream comprising glycols and one or more monosaccharide from the second reaction zone; iv) providing a portion of said product stream for separation and purification of the glycols contained therein; and v) recycling the rest of the product stream to the first reaction zone.
