工艺因素对神东煤直接液化性能的影响

摘要

The direct liquefaction performance of Shendong coal was systemactically investigated in a batch autoclave. The results showed that with increasing of temperature, the total conversion and gas yield are also increasing, PAA yield is decreasing, oil yield is increasing and then decreasing; with increasing of reaction time, the total conversion, gas yield and oil yield are also increasing, PAA yield is decreasing; the suitable reaction temperature is 455 ℃, and reaction time is 120 min.%采用间歇式高压釜,模拟示范工程反应条件,在不同反应温度和停留时间下,考察了神东煤直接液化性能.结果表明,随着反应温度的提高,转化率增加,油产率先增加后降低,气产率增加,沥青质产率减少;随着停留时间的增加,转化率增加,油产率和气产率均增加,沥青质产率下降;适宜的反应温度和停留时间分别为455℃和120 min.
