| 摘 要： | 提出了一种纤维素催化热解制备左旋葡萄糖酮（LGO）的方法。通过Py-GC/MS实验，研究了纯纤维素快速热解的产物分布，以及热解温度、热解时间对纤维素生成LGO的影响；将固体超强酸（SO42-/TiO2和SO42-/ZrO2）和纤维素按1∶1的质量比机械混合后进行快速热解，考察了固体超强酸的催化对热解产物的影响。结果表明，纯纤维素快速热解时，主要在低温和中温的过渡温度区域内，同时发生脱水和解聚反应形成LGO；在固体超强酸的催化作用下，明显促进了LGO的形成，相对质量分数最高达60%以上。

| Abstract: | The pyrolysis of cellulose to produce levoglucosenone(LGO) with solid superacids(SO42-/TiO2 and SO42-/ZrO2) as catalyst was investigated by Py-GC/MS.Non-catalytic pyrolysis of pure cellulose was firstly carried out to reveal the effects of pyrolysis temperature and time on the formation of LGO.Then the mechanic mixture of cellulose with an equivalent mass of the superacids(SO42-/TiO2 or SO42-/ZrO2) was subjected to fast pyrolysis to investigate their catalytic effect on the pyrolytic products.The results in... |
