Abstract

Conventional thermal treatment, microwave baking method and chemical treatment（alkali and acid） combined with microwave baking method are used to bake and modify cotton stalks at 200 ℃, and their structures are characterized by FTIR and XRD. Then the pyrolysis characteristics of the modified samples are further analyzed by TG-FTIR and PY-GC/MS. The results show that the pretreatment schemes optimize the structure of cotton pole and improve the pyrolysis characteristics. The effect of microwave baking is better than that of conventional baking, and the reaction characteristics can be further regulated based on microwave baking combined with alkali and acid treatment.
