英文摘要A series of anhydrous closed-system pyrolysis experiments were performed on pure pristane and octacosane and a sample from the Maoming oil shale to measure the effect of thermal maturation on pristane and phytane carbon isotopic fractionation compared with individual n-alkanes. The result showed that pyrolysis of pure pristane and octacosane caused 1.8 parts per thousand and 5.1 parts per thousand increase in delta C-13 values, respectively. Experiments on the oil shale sample showed 2.0 parts per thousand and 2.2% variations in pristane and phytane delta C-13 values, respectively, but an average 5.5% enrichment in C-13 for the individual n-alkanes. This indicates that the effect of thermal maturation on pristane and phytane delta C-13 values is weaker compared with n-alkanes. The results further suggest that the stable carbon isotopic distribution of pristane and phytane can be used as a correlation tool.
