摘要:In order to investigate the biochar utilization value and preparation conditions of Myriophyllum spicatum after harvested. The thermal decomposition characteristics of Myriophyllum spicatum was studied via synchronous thermogravimetric-differential thermal analysis (TG-DTA). The results show that the thermal decomposition process of Myriophyllum spicatum could be divided into four stages under nitrogen atmosphere. Most of the decomposition occurred in the third (211~343°C) and fourth (343~1000°C) stages with an average weight loss of 34.6% and 33.0%, respectively. The effect of heating rate on thermal decomposition process was not obvious. The apparent activation energies obtained by Kissinger method and FWO peak maximum evolution method were 175.26 kJ/mol and 175.67 kJ/mol, respectively, which indicated that this two methods were suitable for the study of pyrolysis kinetics of Myriophyllum spicatum.
