  • Patent number: 7708877
    Abstract: A new residuum full hydroconversion slurry reactor system has been developed that allows the catalyst, unconverted oil and converted oil to circulate in a continuous mixture throughout an entire reactor with no confinement of the mixture. The mixture is partially separated in between the reactors to remove only the converted oil while permitting the unconverted oil and the slurry catalyst to continue on into the next sequential reactor where a portion of the unconverted oil is converted to lower boiling point hydrocarbons, once again creating a mixture of unconverted oil, converted oil, and slurry catalyst. Further hydroprocessing may occur in additional reactors, fully converting the oil. The oil may alternately be partially converted, leaving a highly concentrated catalyst in unconverted oil which can be recycled directly to the first reactor. Fully converted oil is subsequently hydrofinished for the nearly complete removal of hetoroatoms such as sulfur and nitrogen.

The exemplified reactor cracks C6 to C20 hydrocarbons, desulfurizes the hydrocarbon stream and reforms the hydrocarbons in the stream to produce hydrogen. In a first reactor stage the steam and hydrocarbon are passed through particulate mixed rare earth metal oxide to crack larger hydrocarbon molecules. In a second stage, the steam and hydrocarbon are passed through particulate material that desulfurizes the hydrocarbon.

  • Patent number: 7569136
    Abstract: A continuous liquid phase hydroprocessing process, apparatus and process control systems, where the need to circulate hydrogen gas through the catalyst is eliminated. By mixing and/or flashing the hydrogen and the oil to be treated in the presence of a solvent or diluent in which the hydrogen solubility is high relative to the oil feed, all of the hydrogen required in the hydroprocessing reactions may be available in solution. The oil/diluent/hydrogen solution can then be fed to a plug flow reactor packed with catalyst where the oil and hydrogen react. No additional hydrogen is required; therefore, the large trickle bed reactors can be replaced by much smaller tubular reactors. The amount of hydrogen added to the reactor can be used to control the liquid level in the reactor or the pressure in the reactor.

  • Patent number: 7517446
    Abstract: A fixed bed hydroprocessing system, and also a method for upgrading a pre-existing fixed bed hydroprocessing system, involves preliminarily upgrading a heavy oil feedstock in one or more slurry phase reactors using a colloidal or molecular catalyst and then further hydroprocessing the upgraded feedstock within one or more fixed bed reactors using a porous supported catalyst. The colloidal or molecular catalyst is formed by intimately mixing a catalyst precursor composition into a heavy oil feedstock and raising the temperature of the feedstock to above the decomposition temperature of the precursor composition to form the colloidal or molecular catalyst in situ. Asphaltene or other hydrocarbon molecules otherwise too large to diffuse into the pores of the fixed bed catalyst can be upgraded by the colloidal or molecular catalyst.

  • Patent number: 7513990
    Abstract: The invention relates to a process for sulfurization of catalysts for hydrotreatment, in particular the catalysts for hydrotreating refractory oxides by sulfurization, in which said catalysts are subjected to a sulfurization stage under a gas atmosphere that contains hydrogen sulfide (H2S), hydrogen (H2), and optionally a cover gas for dilution and in which the H2S/H2 molar ratio is more than 4 and the H2S partial pressure is at least equal to 1 kPa. Said sulfurization stage can be carried out in the hydrotreatment unit (sulfurization in situ) or, prior to the charging of the catalyst, in the hydrotreatment unit (sulfurization ex situ) and is generally carried out at a temperature of less than 600° C., preferably less than 500° C. The invention also relates to the catalysts that are sulfurized by said sulfurization process and their use for hydrorefining and/or hydroconversion/hydrocracking of hydrocarbon feedstocks.
