重质油与长焰煤共加氢反应性能
|
摘要
将高温煤焦油、催化裂化油浆分别与新疆长焰煤进行共处理实验,考察了实验条件对共处理反应性能的影响。综合分析共处理条件对原料油转化率、油产率、气产率和沥青质产率的影响规律,得到合适的实验条件为:催化剂质量分数1%,重质油与长焰煤质量比2∶1,反应温度450℃,氢初压10 MPa,反应时间120 min。对煤-油共处理产物进行蒸馏特性分析可知:高温煤焦油共处理产物主要集中在低于230℃馏分,收率为35.14%;催化裂化油浆共处理产物主要集中在170～370℃和370～500℃馏分。
Co-hydrogenation of high temperature coal tar and FCC slurry with Xinjiang long flame coal were carried out. The effects of test conditions on co-treatment reaction performance was investigated. The influences of co-treatment conditions on the feed oil conversion, oil yield, gas yield and asphaltene yield were comprehensively analyzed. The optimized experimental conditions were confirmed as follows: catalyst mass fraction of 1%, ratio of oil to coal of 2∶1, reaction temperature of 450 ℃, initial hydrogen pressure of 10 MPa, reaction time of 120 min. The distillation characteristics of co-processing products were analyzed. The products of coal-derived oil are mainly concentrated in fractions of less than 230 ℃ with a yield of 35.14%. The products of FCC slurry are mainly concentrated at 170-370 ℃ and 370-500 ℃, respectively.
