Resumen:
A new series of catalysts based on noble metal have 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 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. Ir/mesoporous materials were prepared by wetness impregnation, using Iridium Acetylacetonate as source of Ir. The Ir/SBA-3 catalyst synthesized by us had the higher activity measured in tetralin hydrogenation at mild conditions. The experimental data was quantitatively represented by a modified Langmuir-Hinshelwood type rate equation. The preliminary results reveal these materials as a promising catalyts for HDS/HDN reactions.
