Abstract: The effect of feed aromaticity on the reactions of vacuum residue hydrotreating was studied. It was found that when blending heavy distillates with high aromaticity into vacuum residue the reactions of hydrodemetallizaion (HDM) and hydrodeasphaltene (HDasp) were significantly promoted, on the contrary, when blending oil with high saturation these reactions were suppressed. The effect of feed aromaticity on the reactions of hydrodesulfurization (HDS) and HDCCR was not significant. The experimental results indicated that the colloid structure of the vacuum residue could be altered by blending oil with high aromaticity, thus the performance of residue hydrotreating was influenced significantly.
