Ir-supported SBA-15 was studied in hydrodenitrogenation (HDN) of quinoline as a model nitrogen compound. The activity was improved when Si-SBA-15 support was modified with Ga and Al. Characterization of the catalysts was performed by XRD, N2 adsorption, XPS, H2 chemisorption, TPR, NMR and Py-FTIR. Dispersion and nature of the iridium species depended on the characteristics of the support. Ga-SBA-15 with 1 wt.% of iridium loading was the most active catalyst for HDN of quinoline. 85% of nitrogen elimination was attained at short time in mild conditions.
