Resumen:
Inorganic hexagonal mesoporous silica (HMS) and aluminum modified HMS
materials (Al-HMS) were prepared and used as supports of transition
metal sulfide hydrodesulfurization (HDS) catalysts based on nickel,
molybdenum, and tungsten as active phase. The samples were characterized
with XRD, HRTEM, TPD, N2 physisorption and UV-Vis. The catalytic
activity of the trimetallic catalysts was performed in the HDS of
dibenzothiophene (DBT). When Al was incorporated into the inorganic
support, important changes and effects were observed on the
physicochemical properties. On the other hand, the incorporation of Al
into the HMS led to a decrease in the reaction rate (k) and a trend
toward a direct path of desulfurization was observed for all materials.
