    Abstract: A mixing device for mixing concurrently-flowing streams of vapor and liquid in a vessel contains flow baffles forming a tangential inlet orifice through which the liquid and vapor streams flow at high flow velocity and in a tangential direction into a swirl box. The high momentum of the streams in the inlet orifice, the tangential direction of the streams, and the large distance between the inlet orifice and the vessel centerline, result in a violent swirling flow and a large number of fluid rotations in the swirl box, thereby thoroughly mixing the streams entering through the inlet orifice. A mixed stream of vapor and liquid exits the mixing device through an outlet opening in the bottom of the mixing device. An impingement plate located below the outlet opening spreads the liquid and decreases the velocity of the mixed stream. The temperature and chemical composition of the mixed stream are equilibrated.

  • Patent number: 8734638
    Abstract: Processes are provided for producing a diesel fuel product having a sulfur content of 15 wppm or less (e.g., 10 wppm or less) from feed sources that include a biocomponent feedstock. The biocomponent feedstock can be initially co-processed with a mineral feed in a fluidized bed stage, such as an ebullating bed processing stage. Ebullating bed processing can mitigate the impact of the biocomponent feed on other hydrotreatment aspects of a diesel boiling range feed. Challenged biocomponent feeds can be handled by introducing the biocomponent feed into the ebullating bed reactor in a manner that reduces the fouling impact of the feed.

  • Patent number: 8702974
    Abstract: A process for desulphurizing hydrocarbons includes passing a mixture of hydrocarbon and hydrogen over a hydrodesulphurization catalyst to convert organosulphur compounds present in the hydrocarbon to hydrogen sulphide, passing the resulting mixture over a hydrogen sulphide sorbent including zinc oxide to reduce the hydrogen sulphide content of the mixture, and passing the hydrogen sulphide-depleted mixture over a further desulphurization material. The further desulphurization material includes one or more nickel compounds, a zinc oxide support material, and optionally one or more promoter metal compounds of iron, cobalt, copper and precious metals. The desulphurization material has a nickel content in the range 0.3 to 20% by weight and a promoter metal compound content in the range 0 to 10% by weight.

  • Patent number: 8702970
    Abstract: A method for hydroprocessing a hydrocarbon feedstock is provided. The method comprises contacting the feedstock with a catalyst under hydroprocessing conditions, wherein the catalyst is formed by sulfiding an unsupported catalyst precursor of the general formula Av[(MP) (OH)x (L)ny]z (MVIBO4), wherein MP is selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof; L is one or more oxygen-containing ligands, and L has a neutral or negative charge n<=0, MVIB is at least a Group VIB metal having an oxidation state of +6; MP:MVIB has an atomic ratio between 100:1 and 1:100; v?2+P*z?x*z+n*y*z=0; and 0?y??P/n; 0?x?P; 0?v?2; 0?z. In one embodiment, the catalyst precursor further comprises a cellulose-containing material. In another embodiment, the catalyst precursor further comprises at least a diluent (binder). In one embodiment, the diluent is a magnesium aluminosilicate clay.

  • Publication number: 20140066674
    Abstract: A new family of coherently grown composites of TUN and IMF zeotypes have been synthesized. These zeolites are represented by the empirical formula. NanMmk+TtAl1-xExSiyOz where “n” is the mole ratio of Na to (Al+E), M represents a metal or metals from zinc, Group 1, Group 2, Group 3 and or the lanthanide series of the periodic table, “m” is the mole ratio of M to (Al+E), “k” is the average charge of the metal or metals M, T is the organic structure directing agent or agents, and E is a framework element such as gallium. These zeolites are similar to TNU-9 and IM-5 but are characterized by unique compositions and synthesis procedures and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for carrying out various separations.

  • Patent number: 8658027
    Abstract: A system and process for desulfurizing a hydrocarbon feed stream containing organosulfur compounds is provided. In general, the system includes a conventional hydrotreating unit through the high pressure cold or hot separator. Aqueous oxidant and an oxidative catalyst are mixed with the hydrotreated hydrocarbon effluent from the high pressure cold or hot separator, and oxidative desulfurization reactions occur in the low pressure separation zone, thereby minimizing or eliminating the requirement of additional oxidative desulfurization reactors.
