Hydroconversion of Vacuum Residue of a Blend of Western Siberian Oils in the Presence of Ex Situ Synthesized Suspensions of Nanosized Catalysts

Abstract

Concentrated suspensions of nanosized МоS₂, МоS₂+Ni₇S₆, Ni₇S₆, Fe_{1– x}S, and (NH₄)_0.25 · WO₃ particles with an average size of 273–364 nm have been synthesized from reverse emulsions of aqueous solutions of molybdenum, nickel, iron, and tungsten salts in the presence of a sulfiding agent and hydrogen in oil vacuum distillation residues and tested in oil vacuum distillation residue hydroconversion running in an autoclave and a pilot flow system. The test results have shown that the highest activity in hydrogenolysis reactions is exhibited by Mo-containing catalysts. The kinetic characteristics have been determined; the heat of the hydroconversion process has been calculated.
