Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a hydrolyzed cellulose system and method. [Prior Art] The depletion of non-renewable resources such as petroleum and medium carbon, and the environmental pollution problems brought about by them make people's use of biomass more and more important. Lignocellulose is one of the most widely distributed and abundant natural resources on the earth. Lignocellulose can be hydrolyzed to obtain oligosaccharides, such as fibrinogen, cellobiose and glucose. These hydrolysates can be further obtained. Important industrial products such as raw alcohol, organic acids, chemicals and ': commonly used fiber (four) hydrolysis methods are (four) hydrolysis and enzyme hydrolysis. The acid hydrolysis rate is high and the operation is easy, but the acid hydrolysis is serious to the reaction equipment rot #, and since it needs to be neutralized, separated and purified after the reaction, a large amount of waste liquid is produced, the post-treatment cost is increased, and the environment is seriously Shock. Cellulose hydrolysis by an enzyme can be carried out not only at normal temperature and normal pressure, but also with a degree of susceptibility and not limited to molecular size. However, the activity of the enzyme and the nature of the product are apt to owe the composition of the cellulose, the pH value of the anti-reservoir liquid, the temperature and the amount of liquid, or the substance thereof, and the price of the enzyme is high, and the price is almost high. It accounts for more than 30% of the total cost. It is difficult to have large-scale industrial applications. Under normal temperature, Changbao, happy # ^ '虱, built a very high dielectric constant. However, although the hydrogen bond is gradually weakened as the temperature rises, hydrogen bonds no longer exist above the critical temperature. Therefore, water also becomes a non-polar substance and can be thoroughly mixed with slave compounds. In addition to dielectric and electricity, other properties such as 144988.doc 201121991, ion product, etc. are also different from the liquid phase. Due to the unique physicochemical properties of supercritical water, the supercritical hydrolysis method has the advantages of high hydrolysis rate, no production of fermentation inhibitors and no use of acid solution, and it takes more than ten hours compared with other hydrolysis methods. The hydrolysis time, the ultra-l boundary hydrolysis method only takes a few seconds to several minutes of hydrolysis time, not only the time of the Tuas start to shrink, but also has the advantage of saving energy and expanding production capacity. Compared with other hydrolysis methods, supercritical water hydrolyzed fibers at a faster rate than other methods. Former prior art reference to the Republic of China patent 34 〇 124 "decomposition of waste" 4, the known method is an ether bond, ester bond, guanamine bond, isocyanate bond of the above-mentioned hydrolyzable bond of the target compound chemical plant The method of disintegrating waste 'by continuously supplying waste to the reactor in a molten state or in a liquid state, while continuously supplying supercritical water or high-pressure high-temperature water to the reactor and bringing the waste into contact with the waste The decomposition of the compound and the recovery of the starting compound of the target compound or a derivative thereof are essential. The prior art refers to U.S. Patent No. 692,182, "Meth〇df〇r ng cellulose", which uses supercritical or subcritical water as a solvent to interrupt the intermolecular hydrogen bond of the indole type cellulose. The cellulose is dissolved in hot water, and the solution is rapidly cooled to room temperature and the pressure is lowered to a normal pressure state, and a low degree of polymerization of π-type cellulose can be found in the solution.
