摘要： 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.

摘要： In a hydrocracking unit, the flash gases from the high-pressure separator are fed to the bottom of an absorption zone where the entering gases are counter-currently contacted with a lean solvent. The lean solvent absorbs away the contained methane, ethane, propane, butanes and pentanes (C1+) from the contained hydrogen. The overhead gas stream from the absorption zone typically contains hydrogen at a purity of 90 to 98 mol %, or even higher, which is fed to the recycle gas stream to provide hydrogen purity in the range of 96 to 99 mol %, thereby providing an increase in the overall efficiency of the hydroprocessor unit. The process can also be employed with hydrotreating, hydrodesulfurization, hydrodenitrogenation and hydrodealkylation reactors.

摘要： 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.

摘要： The present invention discloses a process for hydroconverting a heavy hydrocarbon chargestock, wherein said chargestock oil is first contacted with a highly active homogeneous hydrogenation catalyst to effect the hydrogenation reaction so that macromolecular radicals of the residue (the precursor of coke) form as less as possible, thereby decreasing the output of coke in the hydrocracking of the residue; when the reaction proceeds to a certain extent, a solid powder is added to adsorb the macromolecular radicals of the residue formed during the reaction and lower their reaction activity, thereby preventing them from further condensing to coke and/or depositing due to polymerization. The synergetic action of the two sorts of substances makes it possible to produce substantively no coke or less coke during the hydrogenation of residue in a suspension bed and prolong the operation lifetime of the unit.

摘要： Embodiments of the present invention are directed to methods for hydroprocessing Fischer-Tropsch products. The embodiments in particular are related to integrated methods for producing liquid fuels from a hydrocarbon stream provided by a Fischer-Tropsch synthesis process. The methods involves separating the Fischer-Tropsch products into a light fraction and a heavy fraction. The light fraction is pre-conditioned to remove contaminants such as CO2 prior to being subjected to hydroprocessing, either separately, or after having been being recombined with the heavy fraction. Any of the hydroprocessing steps may be accomplished in a single reactor.
