    • This process involves feeding cellulose into an extruder with an acid solution. The extruder is comprised of a screw and a barrel. The screw is rotated so as to pressurize the cellulose, and the cellulose undergoes acid hydrolysis and forms microcrystalline cellulose. The invented process can be accomplished by using pure cellulose or a lignocellulosic material as the starting material. If a lignocellulosic material is used, then a basic solution is added to it and the lignocellulosic material is fed through an extruder so as to obtain a mixture comprising lignin, hemicellulose and cellulose. The lignin and hemicellulose are extracted and the remaining cellulose is processed, as discussed previously, to form microcrystalline cellulose.
    • 该方法包括用酸溶液将纤维素加入到挤出机中。 挤出机由螺杆和筒组成。 旋转螺杆以对纤维素加压,并且纤维素经历酸水解并形成微晶纤维素。 本发明的方法可以通过使用纯纤维素或木质纤维素材料作为原料来实现。 如果使用木质纤维素材料,则向其中加入碱性溶液,并将木质纤维素材料通过挤出机进料,以获得包含木质素,半纤维素和纤维素的混合物。 提取木质素和半纤维素,如前所述处理剩余的纤维素以形成微晶纤维素。
