Patent number: 8519011Abstract: Disclosed is a process for converting synthesis gas to liquid hydrocarbon mixtures useful in the production of fuels and petrochemicals. The synthesis gas is contacted with at least two layers of synthesis gas conversion catalyst wherein each synthesis gas conversion catalyst layer is followed by a layer of hydrocracking catalyst and hydroisomerization catalyst or separate layers of hydrocracking and hydroisomerization catalysts. The process can occur within a single reactor, at an essentially common reactor temperature and an essentially common reactor pressure. The process provides a high yield of naphtha range liquid hydrocarbons and a low yield of wax.Type: GrantFiled: August 11, 2011Date of Patent: August 27, 2013Assignee: Chevron U.S.A. Inc.Inventors: Robert J. Saxton, Charles L. Kibby, Kandaswamy Jothimurugesan, Tapan Das

Patent number: 8506910Abstract: A process and system for producing high octane fuel from carbon dioxide and water is disclosed. The feedstock for the production line is industrial carbon dioxide and water, which may be of lower quality. The end product can be high octane gasoline, high cetane diesel or other liquid hydrocarbon mixtures suitable for driving conventional combustion engines or hydrocarbons suitable for further industrial processing or commercial use. Products, such as dimethyl ether or methanol may also be withdrawn from the production line. The process is nearly emission free and reprocesses all hydrocarbons not suitable for liquid fuel to form high octane products. The heat generated by exothermic reactions in the process is fully utilized as is the heat produced in the reprocessing of hydrocarbons not suitable for liquid fuel.Type: GrantFiled: April 20, 2012Date of Patent: August 13, 2013Assignee: CRI EHFInventors: Shwetank Singh, Omar Freyr Sigurbjornsson, Kim-Chinh Tran

Patent number: 8461220Abstract: A method is provided for converting synthesis gas to liquid hydrocarbon mixtures useful as distillate fuel and/or lube base oil containing no greater than about 25 wt % olefins and containing no greater than about 5 wt % C21+ normal paraffins. The synthesis gas is contacted with a synthesis gas conversion catalyst comprising a Fischer-Tropsch synthesis component and an acidic component in an upstream catalyst bed thereby producing a wax-free liquid containing a paraffin component and an olefin component. The olefin component is saturated by contacting the liquid with an olefin saturation catalyst in a downstream catalyst bed.Type: GrantFiled: June 10, 2010Date of Patent: June 11, 2013Assignee: Chevron U.S.A. Inc.Inventors: Charles L. Kibby, Robert J. Saxton, Kandaswamy Jothimurugesan, Tapan K. Das
