Aromatics saturation by sulfided NickelMolybdenum hydrotreating catalysts

The effect of H 2S on the rates of toluene hydrogenation of sulfided Mo, Ni, NiMo and NiMoP/alumina catalysts has been determined at 6 MPa, 350°C over a large range of H 2S partial pressure. In those conditions, Ni/alumina is nearly inactive. For the three other catalysts, similar trends are foun...

Description
Summary:The effect of H 2S on the rates of toluene hydrogenation of sulfided Mo, Ni, NiMo and NiMoP/alumina catalysts has been determined at 6 MPa, 350°C over a large range of H 2S partial pressure. In those conditions, Ni/alumina is nearly inactive. For the three other catalysts, similar trends are found with in particular no effect of H 2S at high partial pressure. In the presence of NH 3, the effect of H 2S remains globally the same.
