    Support and Pretreatment Effects on the Hydrotreating Activity of SBA-15 and CMK-5 Supported Nickel Phosphide Catalysts.

  • Original language description

    Ni2P and Ni12P5 containing catalysts were prepared by impregnation of oxidic precursors on a SBA-15 or CMK-5 nanoporous carbon. X-ray diffraction (XRD) and 31P solid-state NMR confirmed the presence of Ni2P and Ni12P5 at initial P/Ni = 2 and 0.5 ratios,respectively. Lower HDS and higher HDN activities of reduced Ni phosphide catalysts in comparison to commercial sulfided NiMo/alumina were observed in simultaneous reaction of thiophene and pyridine reactions at 320 degree C and 20 bar. Higher activitieswere found on the silica than on the carbon supported catalysts.

    Vliv nosiče a aktivace na hydrorafinační aktivitu fosfidu niklu naneseného na SBA-15 a CMK-5.

  • Czech description

    Katalyzátory obsahující Ni2P and Ni12P5 byly připraveny impregnací oxidických prekursorů na SBA-15 a nanoporezním uhlí CMK-5. XRD a 31P NMR pevné fáze potvrdily přítomnost Ni2P a Ni12P5 při počátečních poměrech P/Ni = 2 and 0.5. Ve srovnání s komerčním sulfidovaným katalyzátorem NiMo/alumina měly redukované Ni fosfidové katalyzátory nižší HDS a vyšší HDN aktivity v simultánní reakci thiofenu a pyridinu při teplotě 320 stupňů C a tlaku 20 barů. Vyšší aktivity byly nalezeny na katalyzátorech připravenýchze siliky než z uhlí.
