在热重红外联用分析仪上开展了纤维素的热裂解失重研究,通过对纤维素热裂解的TG和DTG曲线以及热解产物的红外析出图谱的分析研究,探讨了纤维素热裂解的二次反应过程及机理,并在经典Broido—Shafizdeh模型的基础上.提出了改进的纤维素热裂解模型。
This paper gives the researches on the pyrolytic cracking theory of cellulose. Through analyzing of the curves of TG and DTG analysis and IR spectrum, we investigate in the process and theory of cellulose pyrolysis, and put forward a new-advocated cellulose pyrolyis model based on the classical Broido-Shafizadeh cellulose pyrolysis model.
