Carbon ordered mesoporous CMK-3 with high surface area and high pore volume promotes a very good dispersion of Pt or Ir monometallic and Pt-Ir-bimetallic crystallites in the carbons framework. High active and stable nanospecies are responsible for the good activity and selectivity found in the hydrogenation of tetralin to decalin in the presence of N as indole and S as dibenzothiophene at mild conditions in a Batch reactor. The catalysts prepared were extensively characterized by XRD, N2 adsorption isotherms, XPS, TEM, ICP, CO Chemisorption and TPR. The analysis showed that the carbon mesoporous structure was maintained after metal incorporation and very high dispersed metal supported catalyst were obtained. The activity was compared using the turn over number and Pt-Ir-CMK-3 was the most active catalyst in presence of the inhibitors. The bimetallic catalyst showed more resistance to inhibition than the monometallic catalysts. The reusability of Pt-Ir-CMK-3 indicates that is a potential catalyst for hydrotreating reactions.
