摘要：
A method and apparatus for contacting and reacting fine cellulosic material with acid to produce partly-hydrolyzed cellulose, in which the cellulose is compressed to form higher density material, resulting in reduced consumption of acid and increased uniformity of reaction times. Cellulosic material, such as ground wood pulp, is compressed to reduce the interstitial spaces therein. The compressed material is contacted with an acid, such as sulfuric acid, which is allowed to wick into the interstitial spaces and react with the cellulose to produce partly-hydrolyzed cellulose.
摘要（中）：
一种使细纤维素材料与酸接触和反应以产生部分水解的纤维素的方法和装置，其中纤维素被压缩以形成较高密度的材料，导致酸的消耗减少并且反应时间的均匀性增加。 纤维素材料如磨木浆被压缩以减少其中的间隙空间。 将压缩的材料与酸（例如硫酸）接触，其被允许吸入间隙空间并与纤维素反应以产生部分水解的纤维素。
