该研究以微晶纤维素作为纤维素的模型物,开展了对亲水改性的磺酸型碳材料在水热条件下催化纤维素水解产生还原糖的研究,考察了亲水改性对催化水解作用的影响,并分析了在改性碳材料催化条件下,反应时间、催化剂用量、反应温度等因素对纤维素水解过程的影响。研究结果表明碳材料的亲水改性能提高催化剂表层的亲水性能,从而提升其催化水解纤维素的性能。在170℃条件下,催化剂投加量为0.2 g,反应时间为10 h时是纤维素水解和还原糖积累的最佳条件。
In this study, microcrystalline cellulose was used as a model substance of cellulose to carry out the study on the hydrolysis of hydrophilic sugars sulfonic acid-type carbon material catalyzed hydrolysis of cellulose under hydrothermal conditions, investigated the effect of hydrophilic modification on the catalytic The effects of reaction time, amount of catalyst, reaction temperature and other factors on the hydrolysis of cellulose were analyzed. The results show that the hydrophilic modification of carbon materials can improve the hydrophilic properties of the catalyst surface, thereby enhancing the catalytic hydrolysis of cellulose properties. At 170 ℃, the catalyst dosage was 0.2 g and the reaction time was 10 h, which was the optimal condition for cellulose hydrolysis and reducing sugar accumulation.
