Fluorescent characteristic of sapropelic coal in pyrolitic simulation on secondary hydrocarbon generation

摘要: 通过对4块腐泥型煤原样及热解模拟残渣样的荧光特征的研究,对腐泥煤二次生烃特征加以探讨,得出主要结论为:(1)当开始二次生烃时,将出现蓝移现象,蓝移现象标志着二次生烃的开始;(2)蓝移现象发生的起始位置(镜质组反射率为标志)及蓝移现象的强度与样品的原始成熟度有密切关系,伴随着原始成熟度的提高,蓝移现象发生的成熟度位置将逐渐后移,其与初始成熟度的差值将先增大后减小,增大与减小的转折点推测位于1.4 6%~1.80%之间。

Abstract: Analyses of secondary hydrocarbon generation in sapropelic coal and its residue from pyrolitic simulation are resulted in two conclusions:(1)While secondary hydrocarbon generation begins,the phenomena of blue shift takes place,it marks the start of secondary hydrocarbon generation;(2)the location (marked with the maturity of vitrinite) and strength of the phenomena generating have affinity with original maturity,with original maturity increasing,the location gradually moves back;the difference between generating maturity and original maturity will increase at first and then decrease,the turning point is suggested in the range of 1.46%~1.80% (Ro,max).
