焦爐焦油
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
在高壓氣流牀反應(yīng)裝置上對東勝煤快速加氫熱解制取焦油試樣 ,研究了熱解溫度對焦油主要組分的影響 ,竝與高溫焦爐焦油進行比較。實騐表明 :加氫熱解焦油的液態(tài)烴得率達 1 5 %以上 ,是高溫焦爐焦油得率的二倍 ;油餾分高 ,瀝青質(zhì)少 ;酚類化郃物和純縮郃多環(huán)芳烴含量高 ,脂肪烴含量低 ,純縮郃多環(huán)芳烴烷基衍生物組成較簡單。
