摘要

采用TG-FTIR研究了纤维素在催化剂作用下的热解过程。三种沸石(HZSM-5、H-β、USY)均能有效抑制纤维素的主要分解,减少含氧化合物(如醛类、酸类和酯类)的生成。HZSM-5的脱氧活性最好。USY催化含氧化合物转化为异烷烃,H-β显著促进CO2的形成。

Catalytic pyrolysis of cellulose with zeolites
TG-FTIR was used to study the pyrolysis of cellulose with catalysts. The three zeolites (HZSM-5, H-β, USY) all inhibit the main decomposition of cellulose and reduced the formation of oxygenated compounds (such as aldehydes, acids and esters) effectively. HZSM-5 has the best deoxygenation activity. USY catalyzes the conversion of oxygenated compounds into iso-alkanes, and H-β promotes the formation of CO2 significantly.
