摘要
The pyrolysis characteristics of municipal solid waste (MSW), cotton straw briquette (CSB) and their blends were investigated by thermogravimetric analysis. The experiments were conducted at three heating rates (10, 20 and 40℃/min) and the working temperature range was between room temperature and 1000℃. And the activation energy during pyrolysis process was calculated by the Kissinger-Akahira-Sunose (KAS) method. The results show that MSW has one more weight loss peak than CSB in the DTG curves at the heating rate of 20℃/min. With the increase of heating rate, the DTG curves of experimental samples are shifted to the high temperature side, and the thermal hysteresis phenomenon is significant. There existed synergistic interaction between the co-pyrolysis process of MSW and CSB, especially at high temperature stage. The kinetic analysis shows that the average activation energy of MSW is higher than that of CSB. When the percentage of CSB is 80%, the average activation energy of the blends reachs the minimum number, which is only 111.25 kJ/mol. ? 2020, Solar Energy Periodical Office Co., Ltd.
