AbstractThe study deals with the hydrotreating of vacuum gas oil with boiling range (611-833K) using trickle bed reactor and a commercial cobalt – molybdenum on alumina as a catalyst with temperature range (583-643K) , liquid hourly space velocity range (1.5-3.75 hr-1) , hydrogen to oil ratio about 250 lt / lt , and hydrogen pressure kept constant at 3.5 MPa.
The results showed that the aromatic content of vacuum gas oil decreased while sulfur removal increased with increasing temperature and decreasing space velocity. The properties, viscosity, density, flash point, and carbon residue of the products are decreased with temperature increasing but the aniline point did the otherwise.
