  • Publication number: 20130334102
    Abstract: The invention is directed towards a method of removing mercury bearing species from a hydrocarbon containing fluid. The method comprises the steps of: i) adding dithiocarbamate polymer to the fluid in an amount such that the number of mercury bonding sites on the polymer exceeds the amount of mercury atoms by at least 10% and ii) removing the mercury bearing dithiocarbamate polymer with a water/oil separation device. The invention relies upon an unexpected reversal in the solubility of dithiocarbamate polymer at very high concentrations. Because of the high solubility the polymer remains within the water phase of the hydrocarbon fluid and can be removed without the need for cumbersome precipitation methods and complicated solid liquid separation devices. As a result, the invention allows mercury contaminated crude oil to be easily rid of its mercury with easy to use equipment already present in a typical oil refinery.

    Abstract: A method for preparing a sorbent composition includes the steps of: (i) applying, from a solution or a slurry, a layer of a copper compound on the surface of a support material, and (ii) drying the coated support material, wherein the thickness of the copper compound layer on the dried support is in the range 1-200 ?m. The precursor may be converted to a sorbent suitable for removing heavy metals from liquids or gases by applying one or more sulphur compounds to sulphide the copper compound and form CuS.

  • 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.

    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 introduced to the ebullated bed system with 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 at least a water-soluble metal precursor and pre-sulfided prior to being introduced with the heavy oil feedstock to the reactor system, or sulfided in-situ in the ebullated bed reactor in another embodiment.

  • Publication number: 20120067785
    Abstract: Trace element levels of heavy metals such as mercury in crude oil are reduced by contacting the crude oil with an iodine source, generating a water soluble heavy metal complex for subsequent removal from the crude oil. In one embodiment, the iodine source is generated in-situ in an oxidation-reduction reaction, by adding the crude oil to an iodine species having a charge and a reductant or an oxidant depending on the charge of the iodine species. In one embodiment with an iodine species having a positive charge and a reducing reagent, a complexing agent is also added to the crude oil to extract the heavy metal complex into the water phase to form water soluble heavy metal complexes which can be separated from the crude oil, for a treated crude oil having reduced levels of heavy metals.

  • Publication number: 20120000828
    Abstract: This invention is directed to hydrodemetallization catalysts and hydrodemetallization processes employing a magnesium aluminosilicate clay. The magnesium aluminosilicate clay has a characteristic 29Si NMR spectrum. The magnesium aluminosilicate clay is the product of a series of specific reaction steps. Briefly, the magnesium aluminosilicate clay employed in the catalyst and process of the invention is made by combining a silicon component, an aluminum component, and a magnesium component, under aqueous conditions and at an acidic pH, to form a first reaction mixture and subsequently the pH of the first reaction mixture is adjusted to greater than about 7.5 to form a second reaction mixture. The second reaction mixture is allowed to react under conditions sufficient to form the magnesium aluminosilicate clay. The resulting magnesium aluminosilicate clay combines high surface area and activity for use in hydrodemetallization catalysts and processes.
