| 摘 要： | 有机-无机相互作用是沉积盆地中普遍存在且不可改变的事实.采用热模拟实验方法,考察了钼、硒和锆等微量元素对褐煤样品热解生烃产物的影响.分析结果表明,除硒元素外,随着钼元素和锆元素的加入,褐煤有机质气态产物的生成量显著提高.通过对液态抽提物的分析,发现微量元素钼、锆和硒均能明显地促进饱和烃和芳烃的降解,从而降低了它们的产率,并在一定程度上加速了有机质的成熟.

| Abstract: | Organic-inorganic interactions are ubiquitous and unalterable in sedimentary basins. In this paper, effects of molybdenum, zirconium and selenium and some other trace elements on pyrogenic hydrocarbon generation of lignite was researched. The results indicated that the trace elements molybdenum and zirconium increased considerably the gas yields of the lignitic organic matter while selenium did not. The analysis of liquid extract showed that all the trace elements molybdenum, zirconium and selenium increase... |
