    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.
