摘要： Biomass pretreatment using anhydrous ammonia is effective in a static reactor vessel when the ammonia can penetrate through the biomass particles or pieces in vapor state, and when biomass is continuously fed and moved through the reactor. To achieve this condition, total system moisture content is kept below 40 weight % based on total mass in the system. The pretreated biomass product is effectively saccharified to produce fermentable sugars for biocatalyst production of a product.

摘要： Disclosed is a method for delignifying lignocellulosic materials by first treating the material with an alkaline solution in the presence or absence of anthraquinone, and then exposing the material to a polyoxometalate. Inclusion of the alkaline pretreatment step allows delignification to take place at high efficiency and affords high residue yields and viscosities.
