The paper describes the study of the gasoline fraction hydrofining on the zeolite-containing alumina catalysts modified with variable valence metals, additives of phosphorus and a rare-earth element. In this work, the new zeolite-containing alumina catalysts were developed: NiO-MoO 3 -E-P-HZSM-HY-Al 2 O 3 , CoO-MoO 3 -E-P-HZSM-HY-Al 2 O 3 and CoO-WO 3 -E-P-Al 2 O 3 -ZSM, where E is a rare-earth element. The research was carried out under high-pressure at the flow installation with a fixed catalyst bed. The smallest residual sulfur content (0.0005%) is observed in hydrotreated gasoline on the catalyst CoO-WO 3 -E-P-HZSM-HY-Al 2 O 3 , which is 2-4 times lower than on the catalysts CoO-MoO 3 -E-P-HZSM-HY-Al 2 O 3 and NiO-MoO 3 -E-P-HZSM-HY-Al 2 O 3 and lower than is limited by the Euro-5 standard. When tested on the NiO-MoO 3 -E-P-HZSM-HY-Al 2 O 3 catalyst, the octane number of the gasoline as a result of hydrotreating increased to 88.6, which is significantly higher than on other catalysts. According to electron microscopy, the catalysts are highly dispersed, the components of the active phase metals are mainly in the oxidized state, forming clusters-associates on the surface. The structure, dispersion and state of the clusters are related to the nature of the catalyst components. The synthesized catalysts make it possible to produce high-octane low-sulfur gasoline that meets European standards.
