将抚顺和茂名两种油页岩样品(铝甑含油率分别为9.9％与8.8％),用HCl及HF处理以除去矿物质,得到含灰3.7％与6.5％的有机质;另又用H_2O_2处理以除去有机质,得到含有机碳小于2.5％的矿物质。校核两者的分析结果,从而确定两种油页岩有机质的含量及其元素组成。从矿物质的红外光谱确认了石英、高岭石、伊利石与蒙脱石为其主要成分。计算出油页岩中粘土矿物的结构水含量约为5％。根据51个油页岩样品的分析数据,提出了从工业分析数据计算有机质含量的经验公式:有机质含量=1-(1.07A+CO_2+0.55S_p);式中A为灰分、CO_2为碳酸盐二氧化碳,S_p为硫铁矿硫。根据有机质的元素分析,两种油页岩均属于高氢碳比、低氧碳比类型。
Samples of two oil shale samples, Fushun and Maoming, with an oil content of 9.9% and 8.8%, respectively, were treated with HCl and HF to remove minerals and obtain organic matter containing 3.7% and 6.5% ash. The other H_2O_2 treatment To remove organic matter, resulting in minerals containing less than 2.5% organic carbon. The results of both analyzes were checked to determine the organic matter content and the elemental composition of the two oil shale samples. From the infrared spectra of minerals confirmed quartz, kaolinite, illite and montmorillonite as its main component. The calculated water content of clay minerals in oil shale is calculated to be about 5%. Based on the analysis data of 51 oil shale samples, an empirical formula for calculating organic matter content from industrial analysis data is proposed: organic matter content = 1- (1.07A + CO 2 + 0.55S_p); where A is ash and CO 2 is carbonate Carbon dioxide, S_p for pyrite sulfur. According to the elemental analysis of organic matter, both oil shale belong to the category of high H / C ratio and low oxygen / carbon ratio.
