ABSTRACT:

The hydrogenation activity of a series of HDS catalysts correlated well with O sub 2 chemisorption and surface dispersion measured by ESCA; however, the HDS activity showed poor correlation with both techniques.  The implication is that hydrogenation most likely takes place at edge sites on the basic MoS sub 2 crystallites and HDS at different, yet unknown site locations. Chemisorption, x ray diffraction and ESCA measurements have demonstrated that MnO is concentrated on the surface of the basic Fe particles in reduced Fe-Mn Fischer Trposch catalysts.
