    • Methods are provided for the efficient fractionation of lignocellulosic biomasses into cellulosic, hemicellulosic and lignin fractions, wherein concentrated organic acid vapors are applied to the biomass at elevated temperatures at the location(s) or near the location(s) where the biomass has been harvested and gathered, to at least partly depolymerize or substantially solubilize the hemicelluloses and lignins in the biomass. The organic acid-treated biomass is in either case then dried and pelletized for extended bulk storage and/or for shipment to a second facility some distance away. The organic acid-treated biomass may be processed into desired chemicals, fuels and/or fuel additives at the local processing site or at a second facility away from the local processing site, or the pelletized material may be used as a ruminant feed locally or at a feedlot some distance removed from the local processing site.
    • 提供了将木质纤维素生物质有效分级成纤维素,半纤维素和木质素级分的方法,其中将浓缩的有机酸蒸气在升高的温度下在生物量已被收获的位置或位置附近施用于生物质 并聚集,至少部分地解聚或基本上溶解生物质中的半纤维素和木质素。 有机酸处理的生物质在任一情况下然后干燥并造粒用于延长的大量储存和/或运送到距离一段距离的第二设施。 有机酸处理的生物质可以在局部加工部位或远离局部加工部位的第二设施处理成所需的化学品,燃料和/或燃料添加剂,或者造粒材料可以在本地或在 一个距离当地加工地点一定距离的饲养场。
