Vv. Korolkov et al., HYDRODEMETALATION OF VANADYLPORPHIRINES ON MO AND NI-MO SULFIDE CATALYSTS SUPPORTED ON SIBUNIT, Kinetics and catalysis, 35(1), 1994, pp. 84-86
The hydrodemetallation (HDM) reaction of VO-tetra(tert-butylphenyl)por
phine on Ni-Mo and Mo catalysts, supported on a carbon carrier of the
Sibunit type, proceeds in the same manner as that on the catalysts sup
ported on mineral carriers. Ni-Mo/Sibunit and Mo/Sibunit catalysts exh
ibit high activity in the conversion of model compounds. A fast activi
ty drop at the initial period, which is typical of the catalysts suppo
rted on alumina, is not inherent to these catalysts.
