MoO3-based HDS catalyst obtained by the polymeric precursor method

The NiCoMo/γ-Al2O3 catalyst was synthesized by polymeric precursor method and it was structurally and morphologically characterized by X-ray diffraction, infrared spectroscopy, nitrogen adsorption measurements. Besides the structural and morphological characterization, a catalytic performance test for the hydrodesulfurization process (HDS) using thiophene was also carried out, in a continuous flow reactor. The method proposed for the synthesis of such a catalyst led to an excellent performance of the HDS process, converting more than 97% of thiophene into iso-butane, 1-butene, n-butane, trans-2-butene and cis-2-butene.
