项目摘要

In this research, the saccharification process by the hot compressed water using a slurry flow pump was examined to achieve the establishment of an efficient conversion system, that put with a main objective of the acquisition of a basic parameter necessary for the process design, and it examined it. The diaphragm type pump that has a new point as a liquid piston was developed for slurry pumping. By application of the new type valve sheet and the shape of checkball in the slurry circulation part, the pump became possible to send up to 25wt% of pulverized rice hull slurry under the pressure condition of SMpa. This fact means the new type pump has a ability of sending a slurry up to the flow properties the dilatant region under high pressure condition. The water pyrolysis reaction part of the reactor examined the temperature rise part when 3/8inch tube was used and the necessary length of a reactive part based on flow rate of 100mL/min, and made the tube type reaction device of 6m in the temperature rise part and 33m in a reactive part for trial purposes with the obtained device constant. When having experimented on the pyrolysis of 10wt% of rice hull up to 200°C for 6 min using the manufactured reactor, It was proven that the whole hemicellulose in rice hull was solubilized and its concentration was much more concentrated than that of percolator reactor. Subsequently, 10wt% slurry prepared from 200'C treatment residue was subjected to 280 ° C for 1 min pyrolysis examination. As a result, glucose was obtained from cellulose in the residue and the lignin content in obtained material was decreased compared to percolator reactor. It will be thought, in the next step of our study, that the establishment of the high efficient pyrolysis system becomes possible by doing a detailed resolution examination concerning a treatment temperature and the residence time in the reactor.

在本研究中，通过使用浆流泵的热压缩水的糖化过程进行了研究，以实现建立一个有效的转换系统，把一个主要目标的过程设计所需的基本参数的获取，并进行了检查。隔膜型泵，有一个新的点，作为液体活塞的泥浆泵开发。通过在浆体循环部分采用新型阀片和止回球形状，使泵在SMpa压力条件下输送高达25wt%的船体浆成为可能。这一事实意味着新型泵具有在高压条件下将浆料输送到流动特性的澄清区域的能力。反应器的水热解反应部分检查了当使用3/8英寸管时的温度升高部分和基于100 mL/min的流速的反应部分的必要长度，并且在所获得的装置恒定的情况下，制作了温度升高部分6 m和反应部分33 m的管式反应装置用于试验目的。用自制的反应器对10wt%的船体在200°C下热解6 min，结果表明，船体中的半纤维素全部溶解，其浓度比蒸发器反应器高得多。随后，使由200 ° C处理残余物制备的10重量%浆料经受280 ° C 1分钟热解检查。结果，与蒸馏器反应器相比，从残渣中的纤维素获得葡萄糖，并且所获得的材料中的木质素含量降低。在下一步的研究中，我们认为，通过对反应器中的处理温度和停留时间进行详细的解析检查，可以建立高效的热解系统。
