High activity of highly loaded MoS2 hydrodesulfurization catalysts supported on organised mesoporous alumina

Organised mesoporous alumina-supported Mo sulfide catalysts were prepared by the conventional impregnation with solution of ammonium heptamolybdate and by the method of thermal spreading Of MoO3. The mesoporous alumina (surface area 400-600 m(2) g(-1), pore diameter 3-4.5 nm) exhibited much higher capacity for dispersion of Mo species than the conventional alumina. The activity in thiophene hydrodesulfurization of highly loaded mesoporous alumina-supported catalysts with the MOO, content of 30 wt.% was almost two times higher than the activity of the conventional industrial Mo/Al2O3 containing 15 wt-% Of MoO3 (C) 2002 Published by Elsevier Science B.V.
