摘要
为了探讨树皮煤的生烃特征,对江西乐平树皮煤进行了3种升温速率下的Rock-Eval热解模拟实验,通过分析热解烃的产率随温度的变化,应用Optkin动力学软件对树皮煤进行热力学参数计算。结果表明:树皮煤的生烃潜力高,活化能分布范围窄,到达相应的温度后能够在短时间内大量生烃。通过与前人研究对比,认为树皮体的活化能分布受热解动力学模型、热解实验温度、升温速率、样品的纯度、成熟度等多种因素影响。
To explore bark coal hydrocarbon generation characteristics, carried out Rock-Eval pyrolytic simulation experiments under 3 heating rates for Leping bark coal from Jiangxi. Through analysis of pyrolytic hydrocarbon yield variation along with temperature, using Optkin kinetic software carried out bark coal thermodynamic parameter computation. The result has shown that bark coal has high hydrocarbon generation potential; distribution range of activation energy is quiet narrow, after reaches corresponding temperature will generate large amount of hydrocarbon within short time. Compared with previous researches, confirmed that the distribution of barkinite activation energy will impact by various factors including pyrolytic kinetic model, pyrolysis experiment temperature, heating rate, sample purity and maturity etc.
