  • Patent number: 8980080
    Abstract: A system and process for integrated desulfurizing, desalting and deasphalting of hydrocarbon feedstocks is provided. A hydrocarbon feedstock, a water soluble oxidant, and a water soluble catalyst can be introduced in a oxidation zone and retained for a period of time sufficient to achieve the desired degree of desulfurization, or introduced directly into the desalting zone along with wash water. Catalyst and dissolved salt are discharged along with the wastewater effluent from the desalting zone. A hydrocarbon stream including converted hydrocarbons and oxidation by-products is passed to a deasphalting zone. In the deasphalting zone, phase separation occurs, whereby a light phase including desulfurized hydrocarbons are produced, and a heavy phase including asphaltenes and oxidation by-products are discharged, e.g., passed to an asphalt pool.

  • Patent number: 8920635
    Abstract: Desulfurization of hydrocarbon feeds is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boils at or above the target cut point temperature. A second fraction boiling below the target cut point temperature is substantially free of refractory sulfur-containing compounds. The second fraction is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level. The first fraction is contacted with gaseous oxidizing agent over an oxidation catalyst having a formula CuxZn1-xAl2O4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOx and low sulfur hydrocarbons. The by-product SOx is subsequently removed, producing a stream containing a reduced level of organo sulfur compounds.

  • Patent number: 8906227
    Abstract: Desulfurization of hydrocarbon feeds is achieved by first contacting the entire feed with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions; a flashing column downstream of the hydrodesulfurization reaction zone fractionates the effluent to obtain a first fraction which contains refractory organosulfur compounds and a second fraction that is substantially free of organosulfur compounds, since the organosulfur compounds boiling in the range of this fraction were the labile organosulfur compounds which were initially removed by mild hydrodesulfurization. The first fraction is contacted with a gaseous oxidizing agent over an oxidation catalyst having a formula CuxZn1-xAl2O4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOx and low sulfur hydrocarbons. The by-product SOx is subsequently removed, producing a stream containing a reduced level of organosulfur compounds.

  • Publication number: 20140322092
    Abstract: A catalytic reforming process for producing gasoline of reduced benzene content includes the steps of reforming a reformer feedstock that includes a naphtha stream to produce a gasoline reformate product stream; splitting the gasoline reformate product stream into one or more relatively benzene-rich fractions and one or more relatively benzene-lean fractions; and hydrogenating the one or more relatively benzene-rich fractions to produce a cyclohexane-rich effluent, at least a portion of which cyclohexane-rich effluent is recycled to constitute a portion of the reformer feedstock.

  • Publication number: 20140251873
    Abstract: Reduction of sulfur-containing and nitrogen-containing compounds from hydrocarbon feeds is achieved by first contacting the entire feed with a hydrotreating catalyst in a hydrotreating reaction zone operating under mild conditions to convert the labile organosulfur and organonitrogen compounds. An extraction zone downstream of the hydrotreating reaction zone separates an aromatic-rich fraction that contains a substantial amount of the remaining refractory organosulfur and organonitrogen compounds. The aromatic-lean fraction is substantially free of organosulfur and organonitrogen compounds, since the non-aromatic organosulfur and organonitrogen compounds were the labile organosulfur and organonitrogen compounds which were initially removed by mild hydrotreating. The aromatic-rich fraction is oxidized to convert the refractory organosulfur and organonitrogen compounds to oxidized sulfur-containing and nitrogen-containing hydrocarbon compounds.

  • Publication number: 20140131255
    Abstract: An oxidative desulfurization process is provided in which gaseous oxidant required for oxidative desulfurization reactions is dissolved in the feedstock upstream of the oxidative desulfurization reactor. Gaseous oxidant is mixed with a generally liquid phase feedstock (and in certain embodiment peroxide precursors are also mixed) in a mixing zone under conditions effective to dissolve the gaseous oxidant in the liquid feedstock. The gaseous oxidant dissolved in the hydrocarbon feedstock provides a gaseous oxidant-enhanced feedstock which is charged to the oxidative desulfurization reaction zone thereby permitting substantially liquid phase operation.

  • Publication number: 20140110308
    Abstract: In an FCC process and system, a whole crude oil feedstock is directly converted into light olefins and other products. The feed is separated into a high boiling fraction and a low boiling fraction, and each fraction is processed in separate FCC downflow reactors. The catalyst, combined from both downflow reactors, is regenerated in a common vessel. The low carbon content in the catalyst particles from the low boiling fraction downflow reactor is insufficient to provide the necessary heat. By combining catalyst particles from the high boiling fraction having high carbon content helps to provide additional heat for regeneration.
