This paper presents options for increasing production of diesel fuel in a refinery by FCC light cycle oil (LCO) hydrotreating together with the straight run gas oil (SRGO). The experiments consist of hydrotreating mixtures of 10, 20% LCO and 90% and respectively 80% SRGO at 360, 380°C, two liquid hourly space velocity 0.9 h-1, 1.2 h-1, pressure 50 bar in the presence of two industrial catalyst type Co/Mo and NiMo. The research has focused on the influence of LCO/SRGO ratio, type of catalyst and hydrotreating conditions on diesel fuel quality compared with characteristics required by standard EN 590.
