N2 - Pure and mixed oxides (Al 2O 3, ZrO 2, Al 2O 3-MgO, Al 2O 3-SiO 2, Al 2O 3-TiO 2, and Al 2O 3-ZrO 2) were prepared by homogeneous delayed precipitation. The synthesized supports were impregnated by incipient wetness method to obtain CoMo catalysts. Both supports and catalysts were characterized by N 2 physisorption, X-ray diffraction, among other techniques. Acid-base properties were studied with isopropyl alcohol and cumene decomposition. It was possible to assess qualitatively that nature of Al-Si and its respective catalyst was mainly acidic. Conversion of isopropyl alcohol leads to the dehydration products, mostly propylene with a low amount of di-isopropyl ether and acetone. The CoMo/Al 2O 3-SiO 2 catalyst showed the highest conversion during cumene cracking. CoMo/Al 2O 3-SiO 2 catalyst also was the most active during thiophene hydrodesulfurization followed by CoMo/Al 2O 3-TiO 2 catalyst.
