The present study is devoted to kinetic modeling of cellulose hydrolysis-dehydration into platform molecules (glucose and 5-hydroxymethylfurfural) over a carbon solid acid catalyst. Cellulose depolymerization and transformations of the main process intermediates were experimentally studied under hydrothermal conditions in pure water over a catalyst based on sulfonated Sibunit material at 180 °C in a batch reactor. Based on the data obtained, the 18-step kinetic scheme of the process which included the main reaction pathways was proposed as well as the reaction constants were determined. Kinetic parameters showed that solid acid carbon catalysts seems to be more suitable than soluble ones for the production of 5-HMF from sugars. The proposed software modeling of cellulose hydrolysis-dehydration described the experimental results obtained with a sufficient accuracy.

固体碳酸催化剂在纯水中纤维素多步水解脱水为平台分子的动力学模型

本研究致力于在碳固体酸催化剂上将纤维素水解脱水成平台分子（葡萄糖和5-羟甲基糠醛）的动力学模型。在间歇式反应器中，在基于磺化Sibunit材料的催化剂上，在纯水中水热条件下，在水热条件下，通过水热条件，对纤维素的解聚和主要工艺中间体的转化进行了实验，研究温度为180°C。根据获得的数据，提出了包括主要反应途径在内的18个步骤的动力学方案，并确定了反应常数。动力学参数表明，固态酸性碳催化剂似乎比可溶性催化剂更适合于由糖生产5-HMF。
