随着石油勘探的深入和发展，煤和含煤沉积的生油问题，已经越来越引起人们的重视。为此，笔者选择了准噶尔盆地侏罗系富氢组份含量高的煤样和富镜质组的煤岩样品，采用快速热解法，对其显微组份和全煤的热解生烃潜势进行了研究。结果表明：（１）Ｒ０值为０．３７～０．３９％的未成熟煤岩样品中，壳质组和镜质组在３５０～４５０℃温度区间有最大热解峰面积Ｓ２０（２）富氢组份含量高的样品中，热解产物以正构烷烃＋正构烯烃为主，其次为芳烃化合物。（３）镜质组或富镜质组的煤岩样品中，Ａ１６００／Ｍｇ值较高时，热解产物在Ｃ６—Ｃ１５范围内，某些芳烃化合物成为主峰。（４）惰性组生烃能力最差，在较高温度下，形成含量很低的正构烷烃和烯烃，或在气态烃范畴产生少量烃类，或基本不产生热解产物。（５）随着加热时间的延长或原煤样品演化程度的升高，烯烃含量减少或消失，可能是干酪根转化过程中的残余氢为烯烃的氢化作用提供了氢源，使烯烃转化为烷烃的缘故。
With the deepening and development of petroleum exploration, the generation of oil from coal and coal deposits has drawn more and more attention. For this reason, the author selected the coal samples of Jurassic hydrogen-rich component and the coal-rock samples of rich vitrinite from Jurassic in Junggar Basin. By means of rapid pyrolysis method, the micro-components and pyrolysis of whole coal The potential has been studied. The results show that: (1) In immature coal rock samples with R0 value ranging from 0.37% to 0.39%, the maximum pyrolysis peak area (S20 (2)) is found between the shell and vitrinite at 350-450 ℃, Among the samples with high hydrogen content, the products of pyrolysis mainly consist of n-alkanes + n-olefins, followed by aromatic compounds. (3) In the vitrinite or vitrinite samples, when the A1600 / Mg value is higher, the pyrolysis products are in the range of C6-C15, and some aromatic compounds become the main peak. (4) Inert group has the poorest hydrocarbon generation ability, and forms relatively low content of n-alkanes and alkenes at higher temperatures, or generates a small amount of hydrocarbons in the gaseous hydrocarbon category, or does not produce pyrolysis products. (5) The decrease or disappearance of alkenes with the increase of heating time or the evolution of raw coal samples may be due to the residual hydrogen in the kerogen conversion process providing a source of hydrogen for the hydrogenation of alkenes, converting olefins to alkanes reason.
