摘 要:鲁南和苏北煤田,在相同煤阶下,强还原型镜质组显微组分及由其组成的太原组煤比弱还原型镜质组显微组分及由其组成的山西组煤具有的较高的氢含量、挥发分产率和焦油产率、较强的粘结性和结焦性及液化性能,从而论证了它们各自的煤质特征及合理利用途径。Abstract This paper studies the chemical technological properties of different types of re-ducing coal and its vitrinites of Taiyuan Formation and Shangxi Formation in Southern partof Norht china. The results shows that, compared the weak reductivity type coal and its vit-rinite in shangxi Formation of Same rank,the strong reductivity type coal and its vitrinite inTaiyuan Formation have higher hydrogen content、volatile matter yield and tar yield,andstronger sticking property ,coking propeerty and liquefacting potential. From this,this paperclemonstrates the characteristic of coal quality and the way of reasonable use of coal fromcoal seam. Kevwords coal vitrinite chemical-technoloyical properties reductibility.
