Abstract
Official abstract text for this publication.
Fermentable sugar useful for the production of biofuels can be produced from biomass by contacting the biomass with a solution containing at least one α-hydroxysulfonic acid. The α-hydroxysulfonic acid can be easily removed from the product and recycled.
First claim
Opening claim text (preview).
We claim: 1. A method comprising: (a) providing a biomass containing polysaccharides; (b) providing ethanol; (c) converting at least a portion of ethanol to acetaldehyde thereby producing an acetaldehyde containing product; (d) contacting said acetaldehyde with SO 2 and water to produce α-hydroxysulfonic acid; (e) contacting the biomass with a solution containing said α-hydroxysulfonic acid thereby hydrolyzing the biomass to produce at least one fermentable sugar containi…
