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

  • 7 Accesses

Abstract

Concentrated suspensions of nanosized МоS2, МоS2+Ni7S6, Ni7S6, Fe1– xS, 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.
