The activity and selectivity of the Mo-Ni catalysts prepared by the impregn
ation of supports (gamma-Al2O3, hydrated titanium dioxide (HTD), and palygo
rskite-montmorrilonite clay (PMC)) are studied in the reactions of black oi
l hydrotreatment. The alumina support provides a higher catalytic activity
in the hydrogenation of aromatics. The highest efficiency in desulfurizatio
n and demetalation of raw materials is achieved when hydrated titanium diox
ide is used as a support. A low efficiency of the PMC-based catalyst is lik
ely explained by the aggregation of the active component during hydrotreatm
ent. The PMC support can be used as an additive to gamma-Al2O3. possible re
asons for the dependence of the catalytic activity on the support are consi
dered for various reactions.
