Preparation and Relative Activity of Nobia-Supported CoMo Hydrodesulfurization Catalysts.
Kaluža, Luděk ; Zdražil, Miroslav
Evaluation of new supports alternative to alumina, for instance: ZrO2, TiO2, active carbon or zeolites, is an important topic of recent research on hydrodesulfurization catalysts. Nb2O5 was also considered as the support of Mo and Co(Ni)Mo sulfides and as a precursor of the active phase, niobium sulfide.

Preparation of Hydrodesulfurization Magnesia Supported Cobalt-Molybdenum Catalysts
Kaluža, Luděk ; Gulková, Daniela ; Vít, Zdeněk ; Zdražil, Miroslav
The aim of the present work was to elucidate the possibility of deposition of molybdenyl- and cobalt- acetylacetonates on the high surface area MgO by impregnation from solutions of these compounds in methanol. The prepared CoMo/MgO catalysts exhibited at least 3.3 fold activities in benzothiophene HDS as the reference industrial CoMo/Al2O3 catalyst.
