摘　　要：以催化裂化油浆和3种不同来源的煤为原料,在高压釜内考察了临氢缓和条件下反应温度对煤-油共炼过程的影响。结果表明:随着反应温度升高,煤的液化率先增加后降低,液化油中汽油馏分(<200℃)含量降低、柴油馏分(200~350℃)含量增加、渣油馏分(>350℃)含量先增加后降低,半焦中灰分的相对含量逐渐增加;对于不同来源和属性的原料煤,反应所得半焦的挥发分和固定碳含量变化趋势有所区别,主要与反应苛刻度、原料属性及不同组分在平行-顺序反应中的生成和转化速率有关。The effects of reaction temperature on coal-oil co-processing were studied using FCC slurry and three kinds of coals from different resources in autoclave under mild hydrogen pressure.The results showed that the liquefaction rate first increased and then decreased,the yield of gasoline(<200℃)decreased,diesel(200—350℃)increased,>350℃residue yield first increased and then decreased while the ash content gradually increased with the increase of temperature.The changing trends of volatile matter and fixed carbon in the semicoke were dependent on coal from different sources,but mainly related to the reaction severity,raw material properties,formation rates and transformation rates of different components during the complex parallel-sequential reactions.
