Abstract
A titanium modified catalyst based on noble metal has been prepared with the main aim of
obtaining thiotolerant catalysts to be used in second stage processes of mild-hydrotreating.
We study the catalytic properties of 1 wt% Ir-containing mesoporous materials modified with
TiO2 in the hydrogenation of tetralin to decalin in the presence of 100 ppm of
dibenzotiophene at 250°C and 15 atm of pressure of hydrogen, using a Parr reactor. Titanium
oxide was added via post synthesis with the purpose of improve iridium dispersion.
Ir/mesoporous materials were prepared by wetness impregnation. The catalyst synthesized by
us had good activity measured in tetralin hydrogenation at mild conditions. The preliminary
results show these materials as a promising catalyts for HDS/HDN reactions.
