Effect of Phosphorus Content in the Support of NiMoW/P–Al2O3 Quaternary Hydrotreating Catalysts on Their Hydrodesulfurization and Hydrogenation Activity
Abstract A set of NiMoW/P–Al2O3 catalysts with different P2O5 concentrations in the support (0, 0.5, 1.0, 2.0, 5.0 wt % P2O5; Mo : W = 1 : 2) has been synthesized using the following precursors: H3PMo12O40 and H3PW12O40 heteropoly acids for MoO3 and WO3, respectively, and nickel citrate for NiO. The morphology and surface composition of the sulfide phase of the samples have been studied by high-resolution transmission electron microscopy and X-ray photoelectron spectroscopy; the catalytic activity of the samples in the dibenzothiophene hydrodesulfurization and naphthalene hydrogenation reactions has been determined.
