  • Patent number: 11274070
    Abstract: Higher mixed alcohols are produced from syngas contacting a catalyst in a reactor. The catalyst has a first component of molybdenum or tungsten, a second component of vanadium, a third component of iron, cobalt, nickel or palladium and optionally a fourth component of a promoter. The first component forms alcohols, while the vanadium and the third component stimulates carbon chain growth to produce higher alcohols.

  • Patent number: 8486259
    Abstract: The invention relates to a bulk catalyst comprising at least 60 wt % metal oxidic particles comprising one or more Group VIII metals and Group VIB metal molybdenum, comprising less than 10 mole % of a second Group VIB metal (relative to the total amount of Group VIB metals) and comprising a Group V metal in an amount less than 10 mole % (relative to the total of the Group VIB metals), which bulk catalyst has been calcined at a temperature below a temperature where the hexagonal metastable crystal structure changes to an inactive crystalline structure, preferably below 450° C. and which bulk catalyst has a metastable hexagonal phase characterized by an X-ray diffraction pattern having reflections at 33-35 and 58-61° 2?. Preferably, the main reflections have a full width at half maximum (FWHM) of less than 2.5.

  • Patent number: 8067331
    Abstract: The invention relates to a nickel tungsten bulk catalyst, to a process for the manufacture of said catalyst and to the use of said catalyst for the hydrotreatment, in particular the hydrodesulphurisation and hydrodenitrogenation of hydrocarbon feedstock. The catalyst comprises nickel tungsten metal oxidic particles obtainable by a process comprising forming a slurry of a first solid metal compound comprising Group VNI metal nickel and a second solid metal compound comprising Group VIB metal tungsten in a protic liquid, reacting the first and second solid metal compounds at elevated temperature whereby the first and second solid metal compounds remain at least partly in the solid state during the entire reaction to form the nickel tungsten oxidic bulk catalyst.
