| 摘 要： | 将纤维素快速热解转化为高价值的左旋葡聚糖和左旋葡萄糖酮是国内外研究热点之一。通过制备及表征碳基固体酸，并优化纤维素催化热解的实验条件，在350℃下，Fe3O4/C700-H3PO4与纤维素以1∶3的比例混合，可以显著提高热解过程中左旋葡聚糖40.7%（质量）]和左旋葡萄糖酮13.5%（质量）]的产率，分别比纯纤维素热解提高了2倍和22倍。该研究对纤维素的定向高值化转化具有指导意义。

| Abstract: | The fast pyrolysis of cellulose into high-value levoglucosan and levoglucosenone is one of the research hotspots at home and abroad. In this paper, carbon-based solid acids catalysts were prepared and characterized, and the experimental conditions of cellulose catalytic pyrolysis were optimized. At 350℃, Fe3O4/C700-H3PO4 mixed with cellulose at a ratio of 1∶3 could significantly increase the yield of levoglucosan 40.7%(mass)] and levoglucosenone (13.5%(mass)], which were 2 times and 22 times higher than that of non-catalytic cellulose pyrolysis, respectively. This study was a guide for the directional value-added utilization of cellulose. |
