SBA-15-Supported Nickel Phosphide Hydrotreating Catalysts.

A series of Ni2P and Ni12P5 catalysts supported on SBA-15 mesoporous silica were prepared. The catalysts exhibited lower HDS, but similar or higher HDN activities than alumina supported NiMo or CoMo catalysts in simultaneous thiophene HDS and pyridin...

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

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 rati...
