中国特高挥发分特高油产率煤的分布及其特征
Occurrence of super high volatile and tar yield coal in China
摘要
Abstract
Based on the research results of Chinese potential coal resource estimation and Chinese special and rare coal resource investigation,and combining with previous studies,the volatile and tar yield of Chinese coal resource in different provinces and geological ages were discussed using the calculation method of weighted average of recoverable deposits.The distribution and genesis of super high volatile and tar yield coal in China were researched.The results show that the weighted average of volatile and tar yield of Chinese coal resource is 30.27％ and 7.66％,respectively.The high-medium and high volatile coal and rich and low tar coal dominate.The super high volatile and tar yield coal occupies about 0.9％ of the total recoverable deposits of Chinese coal,and they are primarily brown coal,long flame coal,gas coal and gas-fat coal.The coal with sapropelite or humossapropelite sandwich and the liptobiolite have higher volatile and tar yield because of rich liptinite components.The correlations between the volatile and tar yield and hydrogen content and hydrogen carbon atom ratio are positive for the same coal class.关键词
