摘要

As a renewable resource, cellulose-based material (CBM) is frequently adopted to prepare functional carbon materials, which have been extensively used in the fields of catalysis, environment protection and energy. It is important for researchers in material field to quickly obtain methods for the carbonization kinetic analysis of CBM. In this work, a framework method for quickly determining carbonization process and kinetics parameters is developed. The new framework method employed inventive initial estimation, binary tree assumption, linear programming together with rigorous experimental verification. According to TG experiment data, CBM is divided into two parts marked by free-ends of raw material (corresponding 10 % with free-end in MCC), which undergo different reaction. The results of optimized model show the isothermal TG data has a high accordance, the max Root Mean Squared Error (RMSE) of 0.01, as well as the max RMSE under constant heating rate is 0.009. Furthermore, as a demonstration of using new framework, carbonization reaction of nanocellulose (NNC) is primitively investigated.
