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.

Abstract: Fischer-Tropsch process for the conversion of carbon monoxide and hydrogen to C5+ hydrocarbon mixtures in which process use is made of Fischer-Tropsch catalyst particles and particles comprising zeolite Y with a water adsorption capacity (25° C., p/p0=0.20) of at least 16 wt %.

Abstract: Fischer-Tropsch process for the conversion of carbon monoxide and hydrogen to C5+ hydrocarbon mixtures in which process use is made of Fischer-Tropsch catalyst particles and fluid catalytic cracking (FCC) catalyst particles. The FCC catalyst can be a fresh FCC catalyst, or an equilibrium catalysts (E-cat).

Abstract: The present invention pertains to a process for the treatment of waste gas, preferably engine exhaust gas, in particular diesel or gasoline exhaust gas, wherein the waste gas is contacted with a zeolite Y which has a unit cell size of 24.17-24.45 Å, a water adsorption capacity (p/p0=0.2, T=25° C.) of at most 5 wt. %, and a silica-alumina molar ratio of at least 40. The zeolite is used in adsorbent or catalytic applications, with catalytic applications particularly including oxidation, NOx conversion, and NOx trapping. The invention also pertains to a unit for use in this application comprising the specified zeolite.

Abstract: The present invention is directed to a catalyst composition for FCC which has high efficiency in the production of light olefins while maintaining the bottoms conversion. The catalyst composition is prepared by: a) ex situ activating an olefin-selective zeolite with at least 10 wt % of a phosphorus-containing compound, calculated as P2O5 based on the total amount of olefin-selective zeolite. b) combining the activated olefin-selective zeolite with 10-40 wt % catalytic cracking component, binder, and 0-25 wt % silica in a slurry, so that the total amount of amorphous alumina present in the final catalyst composition is at least 10 wt %, and c) spray-drying the slurry to form catalyst particles.

Abstract: The invention pertains to a catalyst at least comprising a hydrogenation metal component and a swelling synthetic clay consisting of elemental clay platelets, with the average diameter of the clay platelets not exceeding 1 micron and the average degree of stacking of the clay platelets not exceeding 20 platelets per stack. The catalyst is especially suitable for the hydroprocessing of hydrocarbon feeds, the term “hydroprocessing” encompassing all processes in which a hydrocarbon feed is treated with hydrogen. The clays which are suitable for use in the catalyst according to the invention may be prepared as described in Netherlands patent application No. 9401433.

Abstract: The invention relates to a hydrocracking catalyst containing at least one hydrogenation metal component, and particles of a cracking component of which at least 50% of the outer surface is coated with a layer of a pre-formed oxide, which layer has a thickness in the range of 10 nm to 5 .mu.m. The cracking component is either a zeolitic cracking component or an amorphous cracking component or a mixture of both. The particles may be coated with oxide by contacting uncoated particles having a mean particle size in the range of 0.1 to 10 .mu.m with an aqueous medium containing particles of the oxide to be provided as the coating having a particle size in the range of 10-5000 nm, with the ratio between the oxide particle size and the mean particle size of the cracking component particles being in the range of 0.001:1 to 0.5:1. The coating oxide is preferably alumina or silica/alumina.
