Hydrocracking (HDC) is one of the most attractive process alternatives for producing light fractions from heavy crudes. The effect of operating conditions on conversion and selectivity of distillate cuts by a new approach of hydrocracking of atmospheric residue was studied. Experimentations were carried out over a commercial nickel-molybdenum on alumina (Ni-Mo/γ-Al2O3) catalyst in a continuous flow trickle bed reactor. It was observed that pressure influence the hydrocracking yields. Also, an increasing in hydrogen concentration in liquid phase has a favorable effect on cracking reactions due to enhancing hydrogenation of coke formed at elevated temperature. The overall conversion and selectivity were highly increased with a significant reduction of heavy metals.
