| 摘 要： | 为了发展油页岩催化热解方法，本文对油页岩中干酪根在催化剂（SnCl2，MoCl5，ZnCl2）作用下的热解转化进行了研究。运用傅里叶变换红外光谱（FT-IR）、X射线衍射（XRD）、热重（TG）分析等手段对样品在较低温度下（350℃）热解前后的半焦产物进行了分析，利用Coats-Redfern方法计算了热解后的残余半焦动力学参数。结果表明，催化剂可以使干酪根在350℃发生热解反应，同时也能够降低残余半焦的活化能，其中SnCl2、MoCl5和ZnCl2催化处理后残余半焦的活化能分别降低15.10、10.66和20.58 kJ/mol。

| Abstract: | The pyrolysis of oil shale in the presence of the catalysis metal chloride (stannous chloride, molybdenum chloride, zinc chloride) was evaluated. Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and thermogravimetric (TG) analysis were conducted to characterize the solid residues. Moreover, the kinetic parameters were calculated using the Coats-Redfern method. The results showed that catalysts can promote the organic conversion to oil and gas at low temperature, and also effect on the activation energy of the solid residues, particularly with stannous chloride, molybdenum chloride and zinc chloride, with which the activation energy decreased about 15.10, 10.66 and 20.58 kJ/mol respectively compared to those with no catalyst therein. |
