Publication number: 20080272030Abstract: A method for producing synthetic fuels is provided. The process can involve the reaction of metals with water to liberate hydrogen, which can attack the feedstock molecules and with elevated temperature and pressure, reform the feedstocks into liquid fuels. These can be used as is or refined and used as gasoline, diesel fuel, aircraft fuel or burned to produce heat for uses such as generating electricity. The process can be environmentally friendly, producing no net greenhouse gases.Type: ApplicationFiled: June 25, 2007Publication date: November 6, 2008Inventors: Jack W. Boykin, Allen W. Boykin

Patent number: 7435332Abstract: This invention relates to a process for cracking hydrocarbon oils. The process comprises contacting a hydrocarbon oil with a catalyst that has been contacted with an atmosphere containing a reducing gas, separating cracked products and the catalyst, and regenerating the catalyst. The catalyst is a cracking catalyst containing a metal component, or a catalyst mixture of a cracking catalyst containing a metal component and a cracking catalyst free of metal component. The catalyst is contacted with the atmosphere containing a reducing gas at a temperature of 100 to 900° C. for at least 1 second, and the amount of the atmosphere containing a reducing gas is not less than 0.03 cubic meters of reducing gas per ton of the cracking catalyst containing a metal component per minute, at a pressure of 0.1-0.5 MPa in the reduction reactor. The process has enhanced capability for desulfurizing and cracking heavy oils.Type: GrantFiled: September 27, 2004Date of Patent: October 14, 2008Assignees: China Petroleum & Chemical Corporation, Research Institute of Petroleum Processing SinopecInventors: Jun Long, Huiping Tian, Yujian Liu, Yuxia Zhu, Zhenyu Chen, Yaoqing Guo, Zhijian Da, Jiushun Zhang, Mingyuan He

Publication number: 20080190812Abstract: Stable catalyst carrier impregnating solutions can be prepared using a component of a Group VIB metal, e.g., molybdenum, at high concentration, a component of a Group VIII metal, e.g., nickel, at low concentration, and a phosphorous component, e.g., phosphoric acid, at low concentration, provided that the Group VIII metal is in a substantially water-insoluble form and a particular sequence of addition of the components is followed, even when a substantially water-insoluble form of the Group VIB component is used. The resulting stabilized impregnating solution can be supplemented with additional Group VIII metal in water-soluble form to achieve increased levels of such metal in the final catalyst. Furthermore, uncalcined catalyst carriers impregnated with the stable solution and subsequently shaped, dried and calcined, have unexpectedly improved performance when used in the hydroprocessing of heavy hydrocarbon feedstocks.Type: ApplicationFiled: April 16, 2008Publication date: August 14, 2008Applicant: Advanced Refining Technologies LLCInventor: Darryl P.

Patent number: 7368090Abstract: An distributor arrangement introduces spent FCC catalyst more uniformly across the dense bed of the regenerator to provide more even contact with regeneration gas in order to avoid hot spots and zones of incomplete combustion. The invention forms a fluidized hopper to collect spent catalyst and a horizontally extended header with multiple horizontally extended outlet arms to place catalyst into the regenerator. The invention may use an aeration means to fluidize the header to further assist catalyst flow. Furthermore, the spent catalyst delivered to the top of the regenerator dense reduces NOx emissions in the flue gas.Type: GrantFiled: August 25, 2004Date of Patent: May 6, 2008Assignee: UOP LLCInventors: Daniel N. Myers, Mikhail Tretyak, Rusty M. Pittman, Steven Niewiedzial
