CATALYST, METHOD OF PREPARATION THEREOF, AND A DIESEL FRACTION HYDRODESULFURIZATION PROCESS Russian patent published in 2008 - IPC B01J23/882 B01J23/883 B01J27/19 B01J32/00 B01J37/02 B01J29/18 C10G45/08

Abstract RU 2314154 C1

FIELD: petroleum processing catalysts.

SUBSTANCE: invention relates to catalysts for deep processing of hydrocarbon stock and can be employed in petroleum processing and petrochemical industries. Particularly, invention provides catalyst for diesel fraction hydrodesulfurization process, which contains, as active component, oxygen-containing molybdenum and cobalt and/or nickel complex compound at Mo/(Co+Ni) atomic ratio 1.5-2.5 and is characterized by specific surface 100-190 m²/g, pore volume 0.3-0.5 cm³/g, prevailing pore radius 80-120 Å. Catalyst support is constituted by alumina or alumina supplemented with silica or montmorillonite. Described are also catalyst preparation procedure and diesel fraction hydrodesulfurization process.

EFFECT: increased catalytic activity and resistance of catalyst against deactivation in presence of diesel fuel hydrocarbon components and sulfur compound of thiophene and its derivatives series.
