US Patent 9656933 Process for the conversion of saccharide-containing feedstock

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.
