Hydrogenation of aromatics by catalytic hydroprocessing is necessary in the upgrading of fossil hydrocarbons into fuels and bases for petrochemistry. In this paper the meaning and applicability are discussed of the “rim-edge” model, the outstanding hydrogenation activities of NiMoS supported on NiSx, and the effect of doping by the hard anion-forming elements phosphorous, boron, and fluorine.
