摘　　要：有机—无机相互作用是沉积盆地内普遍存在且不可改变的事实。本文采用热模拟实验方法,论述了微量元素M o对褐煤样品热解生烃产物的影响。结果发现:M o元素的加入,增大了褐煤热解气态产物的产率,却降低了液态烃类的产率,同时,M o元素对热解液态抽提物族组分的组成也产生了一定的影响,使产物中芳烃的产率有所减小,从而导致了饱芳比的增加。Organic-inorganic interactions are ubiquitous and unalterable in sedimentary basins. The effect of the trace element molybdenum on the hydrocarbon generation from lignite by pyrolysis is studied using thermal simulation experiments. From the experiments, an increase of gas yields and a decrease of chloroform bitumen ＂A＂ were observed, indicating that the trace element molybdenum catalyzed the process. Further investigations show that the yields of aromatic hydrocarbons decrease and the weight ratio of saturated to aromatic hydrocarbons increases because of the addition of molybdenum.
