Abstract

Irresp. of the application of carbon or alumina as a support, the local structure of the Co-sulfide phase formed during sulfidation of Co and CoMo catalysts is the same. A relation is found between the quadrupole splitting (Q.S. value) of the Co-sulfide phase and its dispersion. The higher the dispersion, the larger the Q.S. value. The so-called Co-Mo-S doublet is obsd. in all cases and it turns out to be related to a highly dispersed Co-sulfide phase instead of a Co, Mo, and S contg. phase. [on SciFinder (R)]
