HYDROTREATING METHOD OF CATALYTIC CRACKING GASOLINE Russian patent published in 2019 - IPC C10G45/08 B01J21/02 

FIELD: technological processes.

SUBSTANCE: invention relates to oil refining. Invention relates to hydrotreatment of catalytic cracking gasoline boiling in range from 0 to 235 °C, containing up to 0.1 % sulfur, having octane number according to the research method up to 95, consisting in passing a mixture of catalytic cracking gasoline and hydrogen through the reactor at temperature of 240–320 °C, pressure 1.5–3.0 MPa, volume ratio hydrogen / raw material 150–350 m³/m³, volumetric feed rate 2–10 h^-1 in the presence of a heterogeneous catalyst containing cobalt, molybdenum and a carrier containing, wt. %: [Co(H₂O)₂(C₆H₅O₇)]₂[Mo₄O₁₁(C₆H₅O₇)₂] 17.4–27.4 %; carrier – balance; wherein the carrier contains, wt. %: aluminum borate Al₃BO₆ with norbergite structure – 5.0–25.0; sodium – not more than 0.03; amorphous aluminosilicate 30–50; γ-Al₂O₃ – balance.

EFFECT: obtaining a product for hydrotreatment of catalytic cracking gasoline – a component of marketable gasoline – with sulfur content of not more than 10 ppm with reduction of the octane number of catalytic cracking gasoline by no more than 1½ points according to the research method.
