特殊原生成因煤的特性和分布研究

Distribution and special characteristics of special coal types originated from syngenetic formation

为实现特殊煤种的合理利用,选择树皮残植煤、角质残植煤、树脂残植煤、孢子残植煤和腐泥煤5种典型的特殊原生成因煤为研究对象,系统研究其性质特殊性,调查5种煤在我国的分布范围及资源量(储量),从能源和工艺2方面讨论了原生成因煤的开发利用价值,并从基础研究—勘查—综合利用等多途径,提出了特殊原生成因煤的合理利用建议。结果表明,特殊原生成因煤具有高挥发分、高氢含量和高H/C原子比等特点,且具有很好的生烃潜力。特殊原生成因煤分布在一定成煤期的部分煤层中。特殊原生成因煤的开发利用潜能很大。应加强基础研究,深入分析特殊原生成因煤的特殊性质,查清资源量,结合我国发展和需求,进行战略性的、持续性的综合利用研究。

The five special coal types originated from syngenetic formation were selected to discuss their specialities on properties,and to investigate their distribution and reserve for studying and usage of special coal types： barkinitic liptobiolith coal,cutinitic liptobiolith coal,suberitic liptobiolith coal,sporinitic liptobiolith coal and sapropelite coal. The utilization values of these special coal types were studied from energy and technology. The reasonable further usages of these coals were suggested combining with various items which were fundamental research,exploration and comprehensive utilization. The results showed that the special coal types originated from syngenetic formation had high volatile matter,high hydrogen content and high H / C atomic ratio,and great hydrocarbon-generation abilities. They were often distributed in some coal seams in certain coal forming period. The usage of the special coal types originated from syngenetic formation was wide concerning on as energy and technology aspects. For reasonable utilization of the special coal types originated from syngenetic formation in future,some measures should be taken such as making fundamental research and investigating coal reserve and so on.
