Patent number: 7767076Abstract: 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.Type: GrantFiled: February 1, 2007Date of Patent: August 3, 2010Assignee: Hitachi, Ltd.Inventors: Nobuyuki Hokari, Tomohiko Miyamoto, Hirokazu Takahashi, Hiromi Koizumi

Patent number: 7763163Abstract: 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.Type: GrantFiled: November 6, 2006Date of Patent: July 27, 2010Assignee: Saudi Arabian Oil CompanyInventor: Omer Refa Koseoglu

Patent number: 7758745Abstract: 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.Type: GrantFiled: March 20, 2008Date of Patent: July 20, 2010Inventor: Shun-Sheng Cheng

Patent number: 7744750Abstract: This invention relates to a process for reducing the Bromine Index of a hydrocarbon feedstock having less than 5 wppm oxygenates-oxygen, comprising the step of contacting the feedstock with a catalyst at conversion conditions to form a first effluent, wherein the catalyst includes a molecular sieve having a zeolite structure type of MWW.Type: GrantFiled: November 17, 2005Date of Patent: June 29, 2010Assignee: ExxonMobil Chemical Patents Inc.Inventors: Stephen H. Brown, James R. Waldecker, Khavinet Lourvanij
