In addition nC〓, nC〓, two isomers of C〓 sterene and three isomers of C〓 isoprenoid hydrocarbons were also identified from aliphatic fraction of pyrolyzed product at 200℃. After pyrolyzed at 300℃, the main aliphatic hydrocarbons were normal alkanes ranged from C〓 to C〓, with C〓 as the main peak and C〓 as the second main peak. Meanwhile, pristane, phytane and C〓 sterane were also detected. In the pyrolysates at 400℃ and 500℃, the content of saturated hydrocarbons decreased, the range of normal alkanes distribution became narrow and the main peak was nC〓. Low concentration of C〓-C〓 steranes was detected and the content of C〓-C〓 increased more.
在200℃热模拟产物饱和烃馏分中除检测出两种长链烯烃外，还检测到正十九碳单烯烃、正三十五碳双烯烃、两个碳二十八甾烯的同分异构体和三个C〓类异戊二烯烷烃化合物同分异构体。300℃模拟产物饱和烃主要为正烷烃，正烷烃的碳数分布范围为C〓-C〓，以C〓为主峰、C〓为次主峰；另外，样品中还检出姥鲛烷、植烷和C〓甾烷等化合物。400和500℃热模拟产物中的饱和烃含量下降，正烷烃系列碳数分布范围变窄，主峰碳后移至C〓，检测到低浓度的C〓-C〓甾烷系列化合物，另外，C〓-C〓藿烷系列化合物含量进一步增加。
