Abstract: 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.

Abstract: 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.
