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 pyridine HDN as well as parallel dibenzothiophene HDS and ortho-methyl aniline HDN. In general, the intrinsic activities of the Ni2P catalysts were higher than those of Ni12P5 catalysts.
Byla připravena série katalyzátorů Ni2P and Ni12P5 nanesených na mesoporezní silice SBA-15. Katalyzátory vykazovaly nižší HDS, ale podobné nebo vyšší HDN aktivity než NiMo a CoMo/alumina katalyzátory při simultánní HDS thiofenu a HDN pyridinu jakožto paralelní HDS dibenzothiofenu a HDN o-metylanilinu. Specifické aktivity katalyzátorů Ni2P byly vyšší než katalyzátorů Ni12P5.
