AbstractA hydrocatalyst for modifying the poor-quality middle distillate oil is prepared from WO3 (10-25 wt.%), MoO3 (8-20 wt.%), NiO (2-4 wt.%), P (1.5-2.5 wt.%) and molecular sieve modified gamma-aluminium oxide as carrier (the rest) through impregnating. Its advantages are high and stable desulfurizing and denitrifying activity, and high effect to increase cetane value by 3-5 units.
