【Abstract】 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.更多还原
