    Abstract The effect of the impregnation stage on the synthesis of NiW sulfide catalysts supported on the ZSM-5 zeolite has been studied. The hydrodearomatization (HDA) of light cycle oil (LCO) in the presence of a catalyst containing nickel and tungsten sulfides as an active phase impregnated onto a micro/mesoporous ZSM-5/SBA-15 support has been conducted. The catalyst has been compared with a commercial AGKD-400 diesel hydrotreating catalyst. It has been found that the impregnation of the supports with a solution containing an oxalic acid additive leads to an improvement in the morphology and composition of the active phase. The deepest hydrogenation is observed at 360°C, 6 MPa H2, and a LHSV = 0.5 h–1. The amount of diaromatic hydrocarbons decreases 12-fold, and the sulfur content decreases by 90%.
