摘要
Abstract
The combustion characteristics of oil sand samples were investigated by the thermogravimetric analysis at different heating rates (i.e., 10 ,20, 50 'C/min). According to the thermogravimetric (TG) and differential thermogravimetric (DTG) curves, oil sand combustion process can be divided into three stages: low temperature section, transition section, high temperature section. The combustion characteristic parameters were calculated. The effect of heating rate and particle sizes were studied. Moreover, the kinetic parameters were obtained by three methods: the C-R, FWO and DEAM method. The results reveal that oil sand have better ignition features and a lower ignition temperature, and the combustion intensity is strong at the last stage of the combustion. The combustion of oil sand can be well described by three models. The result shows that every stage of combustion reaction is described in various reaction orders by using the C-R method. However, the results of DEAM and FWO method can reflect the instantaneous characteristic of combustion reaction perfectly, the activation energy increases in low temperature and high temperature period of combustion, the activation energy changes gently in transition section.关键词
