    • The process includes pretreating the biomass with a first basic solution such as sodium hydroxide and mechanically altering the fibers to provide a fluidized biomass. The fluidized biomass is then subjected to high frequency pulses and shear forces without denaturing the individual components of the biomass. The biomass is then subjected to compressive force to separate a first liquid fraction from a first fractionated biomass. The first fractionated biomass may again then be subjected to the same high frequency pulses and shear forces as previously, particularly if there are hemicellulose and/or sugars still present in the first fractionated biomass. Compressive forces are used to separate a second liquid fraction from a second fractionated biomass. The second fractionated biomass is subjected to oxidation such as with hydrogen peroxide at a pH of 8 to 12. The second fractioned biomass is then subjected to compressive forces to separate one or more water insoluble components of the biomass in water soluble form.
    • 该方法包括用第一碱性溶液如氢氧化钠预处理生物质,并机械地改变纤维以提供流化的生物质。 然后将流化的生物质经受高频脉冲和剪切力,而不使生物质的各个组分变性。 然后对生物质进行压缩力以将第一液体馏分与第一分馏生物质分离。 第一分馏生物质可以再次经受与先前相同的高频脉冲和剪切力,特别是如果在第一分级生物质中仍然存在半纤维素和/或糖。 压缩力用于将第二液体馏分与第二分馏生物质分离。 第二分级生物质经过氧化,例如用8至12的pH的过氧化氢。然后将第二分级的生物质进行压缩力,以分离水溶性形式的生物质的一种或多种不溶于水的组分。
