| 20110220547 | TARGETED DESULFURIZATION PROCESS AND APPARATUS INTEGRATING OXIDATIVE DESULFURIZATION AND HYDRODESULFURIZATION TO PRODUCE DIESEL FUEL HAVING AN ULTRA-LOW LEVEL OF ORGANOSULFUR COMPOUNDS - Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boil 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 an oxidizing agent and an active metal catalyst in an oxidation reaction zone to convert the refractory organosulfur compounds to oxidized organosulfur compounds. The oxidized organosulfur compounds are removed, producing a stream containing an ultra-low level of organosulfur compounds.

| 20140110308 | PROCESS FOR HIGH SEVERITY CATALYTIC CRACKING OF CRUDE OIL - 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. | 04-24-2014 |
| 20140131255 | OXIDATIVE DESULFURIZATION PROCESS AND SYSTEM USING GASEOUS OXIDANT-ENHANCED FEED - 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. | 05-15-2014 |
| 20140197074 | TARGETED DESULFURIZATION PROCESS AND APPARATUS INTEGRATING GAS PHASE OXIDATIVE DESULFURIZATION AND HYDRODESULFURIZATION TO PRODUCE DIESEL FUEL HAVING AN ULTRA-LOW LEVEL OF ORGANOSULFUR COMPOUNDS - 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 Cu | 07-17-2014 |
| 20140251872 | INTEGRATED DESULFURIZATION AND DENITRIFICATION PROCESS INCLUDING MILD HYDROTREATING OF AROMATIC-LEAN FRACTION AND OXIDATION OF AROMATIC-RICH FRACTION - Deep desulfurization of hydrocarbon feeds containing undesired organosulfur and organonitrogen compounds to produce a hydrocarbon product having low levels of sulfur-containing and nitrogen-containing compounds, is achieved by first subjecting the entire feed to an extraction zone to separate an aromatic-rich fraction containing a substantial amount of the refractory organosulfur and organonitrogen compounds and an aromatic-lean fraction containing a substantial amount of the labile organosulfur and organonitrogen compounds. The aromatic-lean fraction is contacted with a hydrotreating catalyst in a hydrotreating reaction zone operating under mild conditions to convert the labile organosulfur and organonitrogen compounds. The aromatic-rich fraction is oxidized to convert the refractory organosulfur and organonitrogen compounds to oxidized organosulfur and organonitrogen compounds. These oxidized organosulfur and organonitrogen compounds are subsequently removed, producing a stream containing reduced levels of organosulfur and organonitrogen compounds. | 09-11-2014 |
| 20140251873 | INTEGRATED DESULFURIZATION AND DENITRIFICATION PROCESS INCLUDING MILD HYDROTREATING AND OXIDATION OF AROMATIC-RICH HYDROTREATED PRODUCTS - 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. These oxidized organosulfur and organonitrogen compounds are subsequently removed. | 09-11-2014 |
| 20140322092 | CATALYTIC REFORMING SYSTEM FOR PRODUCING REDUCED BENZENE GASOLINE - 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. | 10-30-2014 |
