  • Publication number: 20140021094
    Abstract: Heavy hydrocarbons contained in FT off gas of a GTL process are removed by bringing the FT off gas into contact with absorption oil, by introducing the FT off gas into a distillation tower, by cooling the FT off gas or by driving the FT off gas into an adsorbent. A burner tip for heating a reformer tube, using FT off gas as fuel, is prevented from being plugged by the deposition of heavy hydrocarbons contained in the FT off gas.

  • Publication number: 20140001089
    Abstract: Process for hydrotreating a heavy hydrocarbon fraction using a system of switchable fixed bed guard zones each containing at least two catalyst beds and in which whenever the catalyst bed that is brought initially into contact with the feed is deactivated and/or clogged during the steps in which the feed passes successively through all the guard zones, the point of introduction of the feed is shifted downstream. The present invention also relates to an installation for implementing this process.

  • Publication number: 20140001095
    Abstract: A gas-liquid catalyzed reaction is performed by introducing at least a portion of the reactive gas into the catalyst as a cross-flow or radial-flow stream. Introducing at least a portion of the reactive gas as a radial flow stream allows the reactive gas to travel through the catalyst bed along a shorter path length. This reduces the pressure drop for the radial flow portion of the gas. The reactive gas can be introduced into the catalyst bed at various heights relative to the height of the catalyst bed.

  • Publication number: 20130081979
    Abstract: This invention is directed to a process for producing a hydroprocessed product. The invention is particularly advantageous in that substantially longer run length can be attained relative to conventional hydroprocessing methods. This benefit is achieved by using a particular solvent as a co-feed component. In particular, the solvent component is comprised of at least one or more supercritical solvent compounds.

  • Publication number: 20130081977
    Abstract: Heavy oil feeds are hydroprocessed in the presence of a solvent and in the presence of a catalyst with a median pore size of about 85 ? to about 120 ? under conditions that provide a variety of benefits. The solvent can be an added solvent or a portion of the liquid effluent from hydroprocessing. The processes allow for lower pressure processing of heavy oil feeds for extended processing times or extended catalyst lifetimes be reducing or mitigating the amount of coke formation on the hydroprocessing catalyst.

    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.

  • Patent number: 8388830
    Abstract: A process is presented for the removal of oxygen from a hydrocarbon stream. The oxygen can react and cause polymerization of the hydrocarbons when the hydrocarbon stream is heated. Controlling the removal of the oxygen from the hydrocarbon stream produces a hydrocarbon stream that is substantially free of oxygen and has a reduced activity for generating undesired compounds.
