  • Patent number: 6802958
    Abstract: The invention pertains to a process for preparing spherical oxide particles comprising the steps of shaping a starting material comprising an oxide hydrate into particles of substantially constant length by leading the material to a set of two rolls rotating towards each other followed by leading the material to a roll equipped with grooves to form rod-type shapes, cutting the rod-type shapes into particles of substantially constant length, converting the thus formed particles into spheres, and heating the particles to convert the oxide hydrate into an oxide. The process results in particles in which there is substantially no difference in density between the core portion and the shell portion of the particles, which results in a high abrasion resistance. The particles prepared by the claimed process are particularly suitable for the preparation of hydroprocessing catalysts, more in particular for the preparation of hydroprocessing catalysts suitable for the hydroprocessing of heavy hydrocarbon feeds.

  • Patent number: 6517705
    Abstract: A catalytic hydrocracking process for the production of lube base oil wherein a hydrocarbonaceous feedstock is contacted with hydrogen and a metal promoted hydrocracking catalyst in a hydrocracking reaction zone at elevated temperature and pressure to obtain conversion to higher hydrogen-content hydrocarbons including lube base oil. The resulting hot, uncooled effluent from the hydrocracking reaction zone is hydrogen stripped in a hot, high pressure stripping zone maintained at essentially the same pressure as the hydrocracking zone to produce a first gaseous hydrocarbonaceous stream and a first liquid hydrocarbonaceous stream. At least a portion of the first gaseous hydrocarbonaceous stream is condensed to produce a second liquid hydrocarbonaceous stream and a second hydrogen-rich gaseous stream. The first liquid hydrocarbonaceous stream is preferably separated at a pressure greater than atmospheric pressure to provide at least one lube base oil product stream.

    Abstract: A process is described that can limit pressure drops during a catalytic hydrotreatment process carried out in a fixed bed reactor. The liquid feed and gaseous reactant are injected into the reactor either side of the bed and flow as a counter-current. Pressure drops are limited by homogeneously mixing solid catalytic and/or inert particles of different diameters in the bed.
