Abstract: This invention relates to a process for the preparation of promoted molybdenum or tungsten sulphide catalysts, the catalysts prepared by such process, and to the use of such catalysts for hydroprocessing processes, particularly hydrotreating. These catalysts are formed by treating molybdenum or tungsten sulphide-containing material (which may be supported) with a low valence promoter metal selected from transition metals particularly Fe, Co or Ni.

Abstract: The present invention provides an improved method for preparing compounds of the formula Mo4S4L6 comprising: contacting a compound having the formula Mo2S4L2, wherein L is a 1,1dithioacid ligand, with a reducing agent having a reduction potential sufficient to reduce Mo(V) to lower oxidation states, especially to Mo(III) and Mo(IV), at a temperature and for a time sufficient to form the Mo4S4L6 compound. Preferably, the Mo2S4L2 compound is dissolved in an organic solvent along with the reducing agent and the solution is heated at temperatures above 25 .degree.C, up to the boiling point of the solvent and, more preferably, at temperatures in the range of from about 50 .degree.C to about 250 .degree.C.

Abstract: In accordance with this invention, there is provided a lubricating composition comprising a major amount of an oil of lubricating viscosity and a minor amount of an additive having the formula Mo2L4 wherein L is a ligand selected from xanthates and mixtures thereof and, in particular, xanthates having a sufficient number of carbon atoms to render the additive soluble in the oil. In general, the xanthate ligand, L, will have from about 1 to 30 carbon atoms.
