    • A method for the dissolving and rapid hydrolyzing of the lignocellulose biomass and the device thereof are disclosed. The lignocellulose biomass is put in the pure water and rapidly heated to 330˜403° C., and then 89˜99% of the lignocellulose biomass is dissolved and rapidly hydrolyzed to saccharide in 3.38˜21.79 s. The following hydrolysis reaction can be carried out under the homogeneous phase condition for the dissolving of the lignocellulose biomass. At the same time, the solvated biomass could be easily used in the high pressure flow reactor to continuously pretreat the biomass and hydrolyze for producing saccharide, other biofuel and product. The present invention doesn't need any catalyst and doesn't pollute the environment, furthermore the process is simple and the cost is low, and it belongs to green, continuable industry encouraged by the state, and a good prospect of market application could be taken on.

    • The invention discloses a method for completely dissolving and rapidly hydrolyzing cellulose, and uses thereof. Cellulose is placed in an acidic aqueous solution with a [H+] concentration of 10−7˜1 M or an alkaline aqueous solution with a [OH−] concentration of 10−7˜1 M as sample A, wherein the volume ratio of solid to liquid is (0.003˜1.05):1. The acidic aqueous solution with a [H+] concentration of 10−7˜1 M or the alkaline aqueous solution with a [OH−] concentration of 10−7˜1 M is heated up to 261˜352 as sample B. Sample A and sample B obtained from step 1 and step 2 are mixed in a reactor to a concentration of cellulose of 0.1%˜35%, the concentration of the mixed solution is adjusted to an acidity of 10−7˜1 M [H+] or an alkalinity of 10−7˜1 M [OH−], and a water density of 587˜997 kg/m3, pressure is set at 6˜584 MPa. The mixture is rapidly heated up to 261˜352 at heating rate of 7.8˜14.8 /s, and then cellulose is dissolved completely in 0.8˜2 sec and hydrolyzed in 5 sec. Using this technique, it is the first time for achieving complete dissolution and rapid hydrolysis of cellulose at a lower temperature, which not only dramatically reduces the cost of hydrolysis but also improves the safety of production and extends the service life of equipment, thus possessing a good application prospect.
    • 本发明公开了一种完全溶解并快速水解纤维素的方法及其用途。 将纤维素置于[H +]浓度为10-7〜1M的酸性水溶液或[OH-]浓度为10-7〜1M的碱性水溶液中作为样品A,其中固体的体积比 液体为(0.003〜1.05):1。 [H +]浓度为10-7〜1M的酸性水溶液或[OH-]浓度为10-7〜1M的碱性水溶液作为样品B加热至261〜352℃。样品A和 将从步骤1和步骤2获得的样品B在反应器中混合至0.1%〜35%的纤维素浓度,将混合溶液的浓度调节至10-7〜1M [H +]的酸度或碱度 的10-7〜1M [OH-],水密度为587〜997kg / m3,压力设定为6〜58MPa。 混合物以7.8〜14.8 / s的加热速率快速加热至261〜352℃,然后将纤维素完全溶解于0.8〜2秒钟,并在5秒钟内水解。 使用这种技术,它是第一次在较低的温度下实现纤维素的完全溶解和快速水解,这不仅大大降低了水解成本,而且提高了生产的安全性并延长了设备的使用寿命,因此具有 良好的应用前景。
