黄县油页岩及其干酪根中含氧官能团的分析

ANALYSIS OF OXYGEN CONTAINING FUNCTIONAL GROUPS IN HUANGX1AN OIL SHALE AND ITS KEROGEN

采用对腐植酸中含氧官能团的分析方法,并做了一些改进,对黄县油页岩及其干酪根中含氧官能团进行了初步分析。结果发现,油页岩中羧基为1.01％,酚羟基为7.85％,羰基为4.55％,酯基为3.03％.黄县油页岩干酪根中聚集了相当量的含氧官能团,如黄县油页岩中含氧官能团以氧百分含量为基准约为15.50～15.70％,其干酪根中含氧官能因氧总量约为13.20％～13.40％.元素分析及显微镜下鉴定结果表明,黄县油页岩干酪根属于Ⅱ_1型干酪根,黄县油页岩是良好的生油岩。

The analysis method of Oxygen-containing functional groups in humic acid is used to analyze the Oxygen-containing functional groups in Huangxian oil shale and its kerogen. The analysis results are as follows; Carboxyl content is 1.01%, pheaol-hydroxyl is 7.85%, carbonyl 4.55%, ester 3.03%. A considerable amount of Oxygen-containing functional groups can be found in th; kerogen of oil shale. The total amount of oxygen in the Oxygen-containing functional groups of Huangxian oil shale is about 15.50%~15.70%, and that in its kerogen is about 13.20%-13.40%. The ultimate analysis and the microscope identification show that the kerogen in Huangxian oil shale is type Ⅱ1, and Huangxian oil shale is a good oil source rock.
