Abstract
The paper investigates the effect of temperature and hydrogen/hydrocarbons (H2/CH) ratio in the hydrodesulfurization process of vacuum gas oil. The tests have been performed at the experimental reactor ”Andreas Hofer”, within the temperature range from 320 to 380°C, with a variable H2/CH ratio from 100 to 300; with a constant space velocity of 1h-1 and a 40 bar pressure.
It has been shown that the increase of temperature and H2/CH ratio is followed by the increase of sulphur removed from the vacuum gas oil. The structural-group analysis has shown the increase of the paraffinic carbon share (%CP) in the entire temperature range. After the initial reduction in the aromatic carbon share (%CA) with regard to the feed, at lower process temperatures, we have noticed its increase with the increase of temperature, particularly pronounced at the highest severity of process conditions.
Also established have been reductions in the value of the products’ physical properties (density, viscosity, molecular mass), with the increase of temperature and H2/CH ratio within the tested area of their values.
