A system and method for producing molybdenum oxide(s) from molybdenum sulfide are disclosed.

The layer material may comprise graphene, chromium and/or molybdenum sulfide (MoS2).

The catalyst precursors can form a hydroprocessing molybdenum sulfide catalyst in heavy oil feedstocks.

The additive consists of a mixture of ferrous sulphide with a molybdenum and/or zinc and/or antimony and/or tungsten and/or titanium sulphide.

According to the invention, the molybdenum sulphide coating contains a mixture of the sulphide phases MoS2 and Mo2S3 with an essentially random orientation (isotropic orientation) of the phase crystals.

The invention also relates to a method for producing the molybdenum sulphide coating by chemical vapour deposition.

The invention relates to a composition comprising a mixture of zinc sulphide (ZnS) and molybdenum sulphide (MoSx) in which the Mo/Zn molar ratio is between 0.01 and 1.9.

To this end, the molybdenum sulfide containing layer consists of an alternating sequence of two layer that are different from one another.

The hydrorefining catalyst has an average lamination number of molybdenum sulfide of more than 1.0 but 1.9 or less.

The invention concerns a method for preparing tungsten sulphide or molybdenum sulphide nanoparticles by mixing two compositions at a temperature lower than the lowest boiling point of the solvents used.

Molybdenum is found in nature in the form of molybdenum sulfide and molybdenum lead.
