Abstract

BASSM, R et al. SUPPORT EFFECT ON CONVERSION OF QUINOLINE OVER ReS2 CATALYST. J. Chil. Chem. Soc. [online]. 2016, vol.61, n.4, pp.3170-3176. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072016000400004.

The conversion of quinoline over ReS2 supported on y-Al2O3, SiO2, ZrO2 and TiO2 catalysts in a batch reactor at 300oC and 5 MPa of hydrogen pressure was studied. The catalysts were prepared by wet impregnation with a loading of 1.5 atoms of Re per nm2 of support. The catalysts were characterized by N2 adsorption, X-ray photoelectron spectroscopy (XPS) and X-ray powder diffraction (XRD). The Re(x)/supports catalysts displayed high activities for the conversion of quinoline, although negligible formation of N-free compounds (hydrodenitrogenation) were observed. The intrinsic activities of ReS2 were modified by the support decreased in the order: Re/TiO2 > Re/ZrO2 > Re/SiO2 > Re/y-Al2O3. The highest activity displayed by the Re/TiO2 catalyst was correlated with the Re dispersion and formation of ReS2 species. Meanwhile, the lower conversion of quinoline over the Re/ZrO2, Re/SiO2 and Re/y-Al2O3 catalysts was related to the combined effect of the textural properties of catalysts and the formation of ReS    species on the supports.

Keywords : Hydrodenitrogenation; ReS2; quinoline; supports.
