在高压气流床反应装置上对东胜煤快速加氢热解制取焦油试样,研究了热解温度对焦油主要组分的影响,并与高温焦炉焦油进行比较。实验表明: 加氢热解焦油的液态烃得率达15%以上,是高温焦炉焦油得率的二倍;油馏分高,沥青质少;酚类化合物和纯缩合多环芳烃含量高,脂肪烃含量低,纯缩合多环芳烃烷基衍生物组成较简单。加氢热解改善了焦油的品质,提高了得率。“,”Tar sample obtained by flash hydropyrolysis (FHP) from Dongshen coal at high pressure entrained reactor was investigated. An effect of falsh hydropyrolysis temperature on main components in tar was studied and the quality of tar was compared with high temperature coke oven tar. The results showed: the yields of liquid hydrocarbon in FHP tar were more than 15%, which is twofold of that in coke oven tar; the FHP tar has superior oil fraction, i.e., minor pitch, superior phenol components and pure condensed polycyclic aromatic hydrocarbon, and minor aliphatic hydrocarbon. The components of the FHP tar were simpler than that of high temperature coke oven tar. Therefore, FHP improved quantity and quality of tar.
