A Мо-containing composite nanocatalyst is synthesized in a hydrocarbon medium containing dissolved low-density polyethylene and is sulfided by dimethyl disulfide. The phase and structural compositions of the catalyst are determined. The activity of the composite nanocatalyst in the hydroconversion of West Siberian vacuum residue is investigated. It is shown that the catalyst performance depends on...
The phase compositions of molybdenum sulfide-based catalysts with various S/Mo ratios which are synthesized ex situ from reverse emulsions of the aqueous solution of ammonium paramolydbate (NH4)6Mo7O24. 4Н2О in the medium of vacuum residue in the presence of a sulfiding component (sulfur) are studied by chemical thermodynamics and X-ray diffraction. Issues related to the interpretation of the phase...
