Abstract
Mixed PMoV heteropoly acids of Keggin structure, H3+xPVxMo12–xO40 (x = 1–3), were synthesized. Alumina-supported sulfide catalysts were prepared by the support impregnation with a solution of mixed heteropoly acids and Co citrate, followed by activation in an H2S stream. The physicochemical characteristics of the catalyst samples were determined, and their catalytic properties in dibenzothiophene hydrodesulfurization and naphthalene hydrogenation were studied. The catalytic system containing CoPVMo11 showed higher hydrogenating and hydrodesulfurizing activity at 300–320°С.
