Abstract：

Xinjiang has abundant coking coal resource,but Xinjiang coke used by Xinjiang coking coals exhibits high reactivity and low strength after reaction.So it is difficult to translate effectively the resource advantage of Xinjiang into cost advantage.In order to obtain the specificity of Xinjiang coking coal,four typical Xinjiang coking coals and another four inland coking coals of same rank were studied by coal properties analysis,vitrinite reflectance analysis and FTIR analysis. The results show that the differences between low-rank Xinjiang coking coal and low-rank inland coking coal are not obvious.Ash and sulfur content of medium-rank Xinjiang coking coal are lower than medium-rank inland coking coal,which is benefit for decreasing ash and sulfur content of coke.Furthermore,medium-rank Xinjiang coking coal has relatively lower mean maximum vitrinite reflectance,maximum thickness of plastic layer and aromatic condensation in comparison with medium-rank inland coking coal,while the amount of branched aliphatic side-chains and hydroxyl of medium-rank Xinjiang coking coal is higher than medium-rank inland coking coal.It indicates that metamorphism degree of medium-rank Xinjiang coking coal is lower than that of medium-rank inland coking coal.The similar phenomenon is also observed in high-rank Xinjiang coking coal.

Key Words： Xinjiang coking coal;coke;coal properties analysis;FTIR;metamorphism degree
