CATALYST, METHOD OF ITS PREPARATION AND PROCESS OF SELECTIVE HYDROCLEANING OF CATALYTIC CRAKING Russian patent published in 2017 - IPC B01J23/88 B01J23/78 B01J27/51 B01J27/19 B01J37/02 C10G45/04 

FIELD: chemistry.

SUBSTANCE: catalyst for the selective hydrotreating of catalytic cracking gasoline, including cobalt, molybdenum, phosphorus or boron, potassium and alumina, is claimed, it contains, wt %: Mo - 4.0-11.0, Co - 1.2-3.5, P or B - 0.1-1.5, K - 0.5-4.5, S - 2.5-8.5, C - 0.3-5.0, Al₂O₃ - the rest, the catalyst has a specific surface of 90-140 m²/g, a pore volume of 0.2-0.8 cm³/g, the average pore diameter is 4.2-10.0 nm. The invention also includes a process for the preparation of a catalyst and a process for the selective hydrotreating of catalytic cracking gasoline.

EFFECT: high depth of hydrodesulfurization, low degree of hydrogenation of olefins and preservation of octane number in the production of ultra-pure hydrogenate.
