Influence of ultrasonic treatment on residue hydrogenation

摘要

摘要: 对四种减压渣油的超声波处理前后渣油加氢反应产物分布研究表明,超声波处理后渣油加氢反应的焦炭和>500℃残渣油收率降低,气体、汽油、柴油和VGO收率提高,轻油产率提高6~10个百分点,渣油转化率增大,轻质化性能明显增强;不同渣油经超声波处理后的加氢反应性能改变不同;利用超声波处理后渣油加氢的虹吸作用模型,从宏观层次解释了超声波改善渣油加氢效果的原因;超声波处理后杂原子的脱除效果均有不同程度的提高,尤其是对金属钒的脱除影响最为明显。超声波处理后加氢残渣油的饱和分和沥青质含量增加,芳香分和胶质的含量减少。

Abstract: The effect of ultrasomic treatment on the hydrotreating of residue was studied using 4 vacuum residues. Ultrasonic treatment can change the average structure of residue and the content of SARA fractions, and the structure of asphaltene at the same time, improving the hydrogenation performance. The hydrogenation of residue after ultrasonic treatment makes a decrease in the yield of coke and residue of above 500℃ but a increase in the yield of gas, gasoline, diesel distillate fractions and VGO and an increase of about 6 to 10 percentage points in light oil yield. The conversion of residue is improved, and the upgrading action is apparent. The upgrading of residue with ultrasonic treatment is related to the material type. The changes can be explained by the syphonage model in a macro level. It is also found that the removal of heteroatom, especially vanadium metal, is improved with the average removal rate of over 96%. After hydrogenation of residue, SARA fractions of residue are changed, the content of saturate and asphaltene is increased, but the aromatic and resin is reduced.
