摘要：

Oil shale obtained from Kalynkara in Kazakhstan was investigated by powder XRD, XRF, SEM, TG-DTA, and EA. The XRD profiles indicated that the oil shale contained quartz (major component), CaSO4 center dot 2H(2)O, and Mg4Al2(OH)(12)CO2 center dot H2O as minerals. The amount of organic matter in the oil shale was determined by TG-DTA and was approximately 19 wt% based on the weight loss in the temperature range of 473-823 K. Moreover, the H/C ratio determined by EA and TG-DTA was 0.86, indicating that the structure of the organic matter was similar to that of coal. We attempted to extract the organic matter from the oil shale in decalin at 373-623 K, but no significant amount of products was obtained.
