Abstract
Concentrated suspensions of molybdenum, nickel, iron, and tungsten sulfide nanoparticles have been synthesized from inverse emulsions of aqueous solutions of molybdenum, nickel, iron, and tungsten salts in the presence of a sulfiding agent and hydrogen in a vacuum residue of oil distillation and have been tested in hydrocracking reactions of a mixture of paraffin wax and heavy cycle oil (HCO). The hydroconversion has been carried out in an autoclave at 445°C and a hydrogen pressure of 7 MPa. The results of the study have shown that the catalytic activity of the synthesized catalysts in cracking reactions increases in the order: MoS2, (MoS2 + Ni7S6), Ni7S6, Fe1 − xS, (NH4)0.25 ⋅ WO3.
