Abstract
Embodiments of the present invention are directed to the conversion of a source material (e.g., a depolymerized oligosaccharide mixture, a monomeric sugar, a hydrolysate, or a mixture of monomeric sugars) to intermediate molecules containing 7 to 26 contiguous carbon atoms. These intermediates may also be converted to saturated hydrocarbons. Such saturated hydrocarbons are useful as, for example, fuels.
Claims19
A process of preparing a saturated hydrocarbon comprising:
- combining a source material with a dicarbonyl under conditions suitable to form an intermediate mixture, the source material comprising a depolymerized oligosaccharide mixture, a monomeric sugar, a hydrolysate, or a mixture of monomeric sugars;
- and
- adding hydrogen and a hydrogenation catalyst to the intermediate mixture under conditions suitable to form the saturated hydrocarbon.
