SULFUR-RESISTANT CATALYST FOR HYDRODESULFURIZATION PROCESSES AND MOTOR FUEL HYDROGENATION (OPTIONS) Russian patent published in 2007 - IPC B01J29/44 B01J21/04 B01J21/16 C10G45/10 

FIELD: desulfurization and hydrogenation catalysts.

SUBSTANCE: invention relates to preparing hydrodesulfurization and dearomatization catalysts useful in processes of deep purification of motor fuels from sulfur-containing compounds and aromatics. A sulfur-resistant catalyst is provided including active component deposited on porous inorganic support including montmorillonite or alumina and characterized by that support is composed of zeolite H-ZSM-5 with Si/Al atomic ratio 17-45 (80-65%) and montmorillonite or alumina (20-35%), while active component is platinum or palladium, platinum and palladium in quantities, respectively, 0.2-2.0, 0.2-1,5. and 0.4-0.2% based on the total weight of catalyst. Described is also catalyst comprising platinum (0.2-2.0%) or palladium (0.2-1.5%), or platinum and palladium (0.4-2.0%) supported by Ca or Na form of montmorillonite, and also catalyst with the same active components supported by zeolite H-ZSM-5 with Si/Al atomic ratio 17-45.

EFFECT: increased sulfur-caused deactivation resistance of catalyst at moderate temperatures and under conditions efficiency in hydrodesulfurization and aromatics hydrogenation processes.
