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
