通过测定在200-600℃炭化竹材得到的固体产物的碳、氢、氧元素的含量及它们的红外光谱,研究了在炭化过程中竹材中半纤维素、纤维素及木素的变化规律。结果表明,结合元素分析,红外光谱分析方法是研究竹材炭化机理的有效手段。在200℃以前,竹材中的半纤维素和纤维素的大量羟基断裂,并结合成水而失去。在200-250℃之间,竹材中的纤维素被降解,其中的吡喃型环也遭到破坏。并且木素中的甲氧基也被脱去。竹材中的木素网状结构在250-400℃之间遭到完全的破坏。竹炭中的碳原子在600℃已基本上完成了芳环化。图3表2参15。 The change rules of hemicellulose, cellulose and lignin in bamboo during carbonization process were studied by measuring the content of carbon, hydrogen, oxygen and the infrared spectra of the solid products obtained from carbonized bamboo at 200-600 ℃. The results show that the combination of elemental analysis, infrared spectroscopy is an effective means to study the carbonization mechanism of bamboo. Before 200 ℃, the hemicellulose in cellulose and cellulose, a large number of hydroxyl fracture, combined with water and lost. Between 200-250 ° C, the cellulose in bamboo is degraded and the pyran ring is also destroyed. And the lignin in the methoxy is also off. The lignin network in bamboo is completely destroyed between 250-400 ° C. The carbon atoms in bamboo charcoal have essentially completed the aromatic cyclization at 600 ° C. Figure 3 Table 2 参 15.
