Preparation of hydrotreating catalysts via an oxalic acid-assisted hydrotherm…

Abstract. An oxalic acid-assisted hydrothermal deposition method to prepare highly dispersed W/γ -Al2O3 and NiW/γ -Al2O3 hydrodesulfurization catalysts without strengthening the metal–support interaction was developed and compared with the conventional impregnation method. The resulting oxidic and sulfided catalysts were characterized, and their catalytic performance was assessed. The r…
