摘要:

用热重分析和热解气质联用研究了蔗渣纤维素、半纤维素综纤维素3种样品的热解规律,并探讨纤维素和半纤维素单组分间的相互作用。结果表明,纤维素和半纤维素单组分间的相互作用体现在对于不同热解产物产生不同作用:呋喃-2-甲醛等产物的生成有促进作用;对左旋葡萄糖和二氧化碳等产物则是先促进后抑制;对乙酸等产物则先抑制后促进。

Abstract:

The pyrolytic characteristics and the products of bagasse cellulosehemicellulose and holocellulose at different temperatures were studied with TG and py-GC/MSand the interaction between cellulose and hemicellulose components were discussed. The result indicated that the interaction between cellulose and hemicellulose components affected differently on different productsIt enhanced the formation of some productssuch as 2-furancarboxaldehydeand it enhanced firstly and then inhibited the formation of some productssuch as carbon dioxide and levoglucosanand inhibited firstly and then enhanced the formation of some productssuch as acetic acid .
