Nanášení CoO a NiO na nosičové monovrstevné MoO3 katalyzátory suspenzní impregnací
Kaluža, Luděk ; Zdražil, Miroslav
The contribution is focused on CoO(NiO) deposition onto supported monolayer MoO3 catalysts applying the principles of slurry impregnation method. Various Co and Ni compounds in their aqueous slurries were tested for reaction with the MoO3 catalysts. The Co(Ni) compounds used were characterized by measuring of their PZC and XRD. The CoO(NiO) deposition on MoO3/Al2O3 extrudates was evaluated using electron probe microanalysis, EPMA. Deposited CoO (NiO) species was found to significantly enhance the activity of the supported MoO3 catalysts in hydrodesulfurization, HDS, of benzothiophene. The activity of the catalysts prepared was comparable with the activity of the reference commercial catalysts.
