Abstract

Hydroconversion of benzo- and dibenzothiophene sulfone on a Ni–Mo sulfide catalyst based on mesoporous aluminosilicate Al-HMS and on unsupported catalysts prepared in situ in the course of decomposition of poorly soluble precursors (molybdenum hexacarbonyl, nickel naphthenate) was studied. Hydrogenation of sulfones was perfpormed at 250, 340, and 380°С and elevated СО pressure in the presence of water ensuring in situ generation of hydrogen via water-gas shift reaction.
