对我国１８种具有代表性的不同煤化程度的煤（Φ３ｍｍ），在氢气氛、０．１ＭＰａ和９００℃条件下进行了热解实验研究。考察了煤化程度对热解转化率和热解产物产率的影响；煤中挥发分与甲烷产率的关系；煤中氧含量与ＣＯ、ＣＯ２产率的关系以及煤种对热解气热值的影响，得到了描述热解气产率与煤中挥发分的关系式。
Eighteen kinds of coal (Φ3mm) with different degrees of coalification were tested in China under hydrogen atmosphere, 0.1MPa and 900 ℃. The effects of the degree of coalification on the conversion rate of pyrolysis products and the yield of pyrolysis products were investigated. The relationship between the volatile content in coal and methane yield, the relationship between oxygen content in coal and CO and CO2 yields, The relationship between pyrolysis gas yield and volatile content in coal was obtained.
