    摘要： The inventive process converts cellulosic biomass into a gel-like state that is readily hydrolyzed by appropriate enzymes. First the biomass is mechanically reduced in size. The biomass is then mixed and kneaded with an aqueous solution of a hydrophilic polymer that acts as a conditioning agent or as a co-solvent. During mixing the cellulose (and hemicellulose) in the biomass swells and becomes hydrated forming a viscous gel-like material. The processed material can then be thinned through the addition of water whereupon hydrolytic enzymes are mixed into the material and rapid hydrolysis into free sugars takes place. Dextrins are effective hydrophilic polymers for conditioning biomass. Polyvinyl alcohol is a particularly effective conditioning agent for use with biomass when converted into a viscous gel by adding borate ions.

    摘要： Cellulosic biomass is reduced to a micropowder with particles having average diameters below 5-10 micrometers with a significant fraction of the particles have diameters below 1 micrometer. Biomass (e.g., wood, agricultural waste or other plant materials) is first processed into pieces having a maximum diameter of about 10 mm. This is then dried to reduce its water content to no more than about 15% by weight and introduced into a disruptor which reduces the particle size to about 1 mm. Next the biomass is processed with a disc mill where edges of rotating discs travel along a groove pressing and squeezing the biomass, thereby breaking the biomass pieces into smaller and smaller particles. The resulting micropowder is extremely susceptible to enzymatic or chemical hydrolysis into constituent sugars. In addition, the micropowder can be suspended in an air stream and burned directly to provide heat to boilers and similar devices.
