摘要: 对桦甸油页岩(OS-R)采用HCl/HF/HNO3处理,分别得到去碳酸盐样品(OS-C)、去碳酸盐及硅酸盐样品(OS-F)以及有机质样品(OS-N),用XRD鉴别其矿物组成,然后通过TG-FTIR-MS研究有机质脱挥发分机理及不同矿物质对挥发分不凝气释放过程的影响。结果表明:黄铁矿的存在使挥发分不凝气体释放的初始温度明显降低,反应更易进行,且使生成的不凝气产量更高,尤其是对不凝气中H2O生成促进作用更显著;硅铝酸盐的存在使不凝气体产量明显减少,提高了不凝气释放的初始温度,减少了不凝气释放的过程时间。然而碳酸盐的存在能增加不凝气产量,使CO2脱出的初始温度更低。

Abstract: Hydrochloric acid,hydrofluoric acid and nitric acid were selected to remove the respective mineral matrix of Huadian oil shale. The samples were examined with XRD to identify mineral composition. The effect of minerals in oil shale on the release of volatile non-condensable gas from organic matter was investigated through the TG–FTIR-MS test. Pyrite decreased initial temperature of release of volatile non-condensable gas from organic matter,making the reaction easier and increasing the yield,especially of H2O. Aluminosilicate decreased non-condensable gas yield,increased initial temperature of release of volatile non-condensable gas and decreased reaction time. Carbonate increased volatile non-condensable gas yield,and decreased the initial release temperature of CO2.

Key words: organic matter, mineral, volatile, non-condensable gas, yield
