  • Patent number: 8628656
    Abstract: Processes for the desulfurization of a cracked naphtha by the reaction of hydrogen with the organic sulfur compounds present in the feed are disclosed. In particular, processes disclosed herein may use one or more catalytic distillation steps followed by further hydrodesulfurization of the naphtha in a fixed bed reactor. It has been found that the formation of recombinant mercaptans in the fixed bed reactor effluent may be reduced or eliminated by reducing the concentration of hydrogen sulfide and/or olefins at the exit of the fixed bed reactor. The reduction or elimination in the formation of recombinant mercaptans may be accomplished by recycling a select portion of the fixed bed reactor effluent to the fixed bed reactor, where the select portion has a relatively low or nil concentration of olefins. Processes disclosed herein may thus facilitate the production of hydrodesulfurized cracked naphthas having a total sulfur content of less than 10 ppm, by weight.

    Abstract: The service life and deactivation rate of a reforming catalyst is improved through use of a new sulfur guard bed containing a chloride additive. This sulfur guard bed, which contains supported CuO material having an increased resistance to reduction, shows such improvement. Thus, the danger of run-away reduction followed by a massive release of water causing process upsets in a catalytic reforming process is practically eliminated. The fact that the guard bed material preserves the active metal phase—copper in an active (oxide) form is an important advantage leading to very low sulfur content in the product stream. The sulfur capacity per unit weight of sorbent is also significantly increased, making this sorbent a superior cost effective sulfur guard product.

  • Patent number: 8236172
    Abstract: A process for reducing the sulfur content of a hydrocarbon stream, including: feeding hydrogen and a hydrocarbon stream including sulfur compounds to a catalytic distillation reactor having one or more hydrodesulfurization reaction zones; concurrently in the catalytic distillation reactor: fractionating the hydrocarbon stream into a heavy fraction and a light fraction; contacting hydrogen and the light fraction to form H2S and a light fraction of reduced sulfur content; recovering the light fraction, H2S, and hydrogen as an overheads; recovering the heavy fraction; heating the overheads to a temperature from 500 to 700° F.; feeding the heated overheads and hydrogen to a high temperature low pressure reactor to form H2S and a reactor effluent of reduced mercaptan content; separating the reactor effluent, H2S, and unreacted hydrogen to form a light hydrocarbon fraction and a fraction including H2S and hydrogen; recycling a portion of the light hydrocarbon fraction to the catalytic distillation reactor.

  • Patent number: 8236262
    Abstract: A particulate desulfurization material includes one or more nickel compounds, a zinc oxide support material, and one or more alkali metal compounds wherein the nickel content of the material is in the range 0.3 to 10% by weight and the alkali metal content of the material is in the range 0.2 to 10% by weight. A method of making the desulfurization material includes the steps: (i) contacting a nickel compound with a particulate zinc support material and an alkali metal compound to form an alkali-doped composition, (ii) shaping the alkali-doped composition, and (iii) drying, calcining, and optionally reducing the resulting material. The desulfurization material may be used to desulfurize hydrocarbon gas streams with reduced levels of hydrocarbon hydrogenolysis.

  • Publication number: 20120168350
    Abstract: An improved process for preparing a slurry catalyst for the upgrade of heavy oil feedstock is provided. The process employs a polar aprotic solvent to mix with the inorganic metal precursor feed to form an oil-dispersible inorganic metal precursor, at a weight ratio of solvent to inorganic metal precursor of 1:1 to 10:1; the oil-dispersible inorganic metal precursor is subsequently sulfided forming the slurry catalyst. In one embodiment, the sulfiding is in-situ upon mixing the oil-dispersible inorganic metal precursor with a hydrocarbon diluent containing a heavy oil feedstock under in-situ sulfiding conditions.

  • Publication number: 20120152805
    Abstract: A method to upgrade heavy oil feedstock using an ebullated bed reactor and a novel catalyst system is provided. The ebullated bed reactor system includes two different catalyst with different characteristics: an expanded catalyst zone containing particulate catalyst having a particle size of greater than 0.65 mm; and a slurry catalyst having an average particle size ranging from 1 to 300 ?m. The slurry catalyst is provided to the ebullated bed system containing the heavy oil feedstock, and entrained in the upflowing hydrocarbon liquid passing through the ebullated bed reaction zone. The slurry catalyst reduces the formation of sediment and coke precursors in the ebullating bed reactor system. The slurry catalyst is prepared from rework materials, which form a slurry catalyst in-situ upon mixing with the heavy oil feedstock.
