Abstract
Methods and compositions for processing biomass using [Co(CN)5]3″ are disclosed. The resulting products include monomeric carbohydrate units that can also be converted to basic alcohols, including ethanol, for a variety of uses including transportation fuels and the generation of electricity.
Claims19
A process for generating monomeric carbohydrates from a biomass feedstock comprising:
- providing a biomass feedstock stream having one or more of cellulose, hemicellulose, amylose, maltodextrin, and mixtures of the same;
- contacting the aqueous feed stock with a pentacyanocobaltate(II) anion catalyst having the formula [Co(CN)5]3− to produce a product stream comprising at least one monomeric carbohydrate.
A composition, comprising:
- biomass having one or more of cellulose, hemicellulose, amylose, maltodextrin, and mixtures of the same;
- pentacyanocobaltate(II) anion catalyst having the formula [Co(CN)5]3−.
