Abstract: The invention provides a process for the catalytic conversion of a saccharide-containing feedstock in a reactor, wherein saccharide-containing feedstock is provided to the reactor as a feed stream through a feed pipe and is contacted with a catalyst system in the reactor, wherein the saccharide-containing feedstock in the feed pipe is maintained at a temperature below the degradation temperature of the saccharide contained therein and a section of the wall of the reactor at the point where the feed pipe enters the reactor is cooled to a temperature below the temperature of the bulk of the reactor and the reactor contents.

Abstract: The invention provides a process for the preparation of monoethylene glycol from sucrose comprising the steps of: i) hydrolyzing sucrose to form a reaction product stream comprising glucose and fructose; ii) separating the reaction product stream comprising glucose and fructose into a fructose or fructose derivative rich stream and a glucose rich stream; and iii) contacting the glucose rich stream with hydrogen in a reactor in the presence of a solvent and a catalyst system with catalytic hydrogenation abilities to produce a product stream comprising monoethylene glycol.
