    Abstract: A process is described for the extractive oxidation of contaminants present in raw fuel streams rich in heteroatomic polar compounds and catalyzed by iron oxides contained in natural limonitic goethite, said process comprising contacting said streams with an oxidation pair which is a peroxide in solution/organic acid in amount of at least 3 and an amount between 0.01 and 10 wt % of an iron oxide, both based on the feed, the iron oxide being made up of a reduced natural limonitic goethite. The goethite reduction by a hydrogen stream has the advantage of lowering the migration of non-contaminating polar hydrocarbons from the fuel stream to the aqueous phase, at the same time obtaining higher mass yield of final product fuel while the level of target contaminants to be removed is maintained relative to the state-of-the-art process.

  • Patent number: 7780847
    Abstract: A process for producing gasoline having reduced sulfur content while maintaining or improving octane rating is provided. A gasoline fraction having a substantial amount of olefinic and sulfur compounds produced from fluidized catalytic cracking or coking is contacted first with an adsorbent to selectively remove alkylated thiophenic, benzothiophene, and alkylated benzothiophenic sulfur compounds. The adsorptively treated gasoline fraction is then introduced into a conventional hydrodesulphurizing catalyst bed with hydrogen for further removal of sulfur compounds. Adsorbent containing alkylated thiophenic, benzothiophene, and alkylated benzothiophenic compounds are regenerated through washing with a hydrocarbon solvent and subsequent drying-out by warming.

  • Patent number: 7776778
    Abstract: X-ray amorphous carbon is formed by evaporating carbonic material. The evaporation of carbonic material is conducted in a helium atmosphere at a supply energy flow in the range of 50 to 300 W/mm2. The energy is generated, for example, by means of an electric arc. The X-ray amorphous carbon has a starting temperature of an air oxidation, Tso, ?320° C.; a temperature of maximal rate of an air oxidation, Tomr, ?590° C.; a temperature of end of an air oxidation, Teo, ?630° C.; an initial rate of non-catalytic hydrogenolysis by molecular hydrogen at 700° C., Vhin, ?2.08% mass of carbon/h. Upon contact in a solution, 1 g of X-ray amorphous carbon consumes an amount equal to or greater than 16 mmole of MnO4? ions. Catalysts based on the X-ray amorphous carbon are used in hydrocarbon dehydrogenation and dehydrocyclization reactions.

  • Patent number: 7767076
    Abstract: The reforming of heavy oil with supercritical water or subcritical water is accomplished by mixing together supercritical water, heavy oil, and oxidizing agent, thereby oxidizing vanadium in heavy oil with the oxidizing agent at the time of treatment with supercritical water and separate vanadium oxide. The separated vanadium oxide is removed by the scavenger after treatment with supercritical water. In this way it is possible to solve the long-standing problem with corrosion of turbine blades by vanadium which arises when heavy oil is used as gas turbine fuel.

  • Patent number: 7763163
    Abstract: A feedstream to a hydrocracking unit is treated to remove or reduce the content of polynuclear aromatics and nitrogen-containing compounds by contacting the feedstream with an adsorbent compound selected from attapulgus clay, alumina, silica gel and activated carbon in a fixed bed or slurry column and separating the treated feedstream that is lower in the undesired compounds from the adsorbent material. The adsorbent can be mixed with a solvent for the undesired compounds and stripped for re-use.

  • Patent number: 7758745
    Abstract: A diesel desulfurization method has various steps including: implementing a modified oxidative desulfurization (UAOD) process. The UAOD has the steps of: mixing diesel fuel with room temperature ionic liquid, oxidant, phase transfer catalyst, and acid catalyst in a tank in a mix; recycling the ionic liquid and recycling the acid catalyst in aqueous phase. A step is to move the sulfur from the diesel fuel in a fluidized bed reactor (FBR) having bed reactor material. The process can be improved with ultrasound during mixing, or a high shear mixer. The bed reactor is preferably acidic alumina for adsorbing oxidized sulfur. The oxidant is preferably hydrogen peroxide (H2O2). The acid catalyst is preferably a mixture of Acetic acid and Tri-fluoro acetic acid.

  • Patent number: 7744748
    Abstract: A process for reducing the quantity of sulphur present in a hydrocarbon feed such as a gasoline or a gas oil, comprises: d) bringing said feed containing sulphur-containing compounds into contact with an adsorbent having a selectivity for sulphur-containing compounds under conditions for producing, at the outlet from the contact zone, a desulphurized effluent which is collected, said adsorption being carried out in the liquid phase or in the gas phase; e) gas phase desorption of the sulphur-containing compounds present on said adsorbent using a hydrogen-containing gaseous fluid derived from a hydrodesulphurization zone to obtain a gaseous effluent comprising hydrogen and desorbed sulphur-containing compounds; sending the gaseous effluent from step b) to said hydrodesulphurization zone and desulphurizing it therein.
