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 and wherein, as the saccharide-containing feedstock is fed through the feed pipe, a solvent stream, initially comprising essentially no saccharide, is fed along the internal walls of the feed pipe.
Claims11
A process for the catalytic conversion of a saccharide-containing feedstock in a reactor to a glycol, wherein saccharide-containing feedstock is provided to the reactor as a feed stream through a feed pipe having a first section and a second section and is contacted with a catalyst system in the reactor and wherein, as the saccharide-containing feedstock is fed through the second section of the feed pipe, a solvent stream, initially comprising essentially no saccharide, is fed along the internal walls of the second section of the feed pipe to provide a co-axial flow of the solvent stream around the saccharide-containing feedstock.
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 and wherein, as the saccharide-containing feedstock is fed through the feed pipe, a solvent stream, initially comprising essentially no saccharide, is fed along the internal walls of the feed pipe, wherein the temperature of the saccharide-containing feedstock is initially below the degradation temperature of the saccharide and the temperature of the solvent stream is initially higher than the degradation temperature of the saccharide.
