Patent number: 10086365Abstract: A method of strengthening a precipitated unsupported iron catalyst by: preparing a precipitated unsupported iron catalyst containing copper and potassium; adding a solution comprising a structural promoter to the previously prepared catalyst; drying the mixture; and calcining the dried catalyst. A method for preparing an iron catalyst, the method comprising: precipitating a catalyst precursor comprising iron phases selected from hydroxides, oxides, and carbonates; adding a promoter to the catalyst precursor to yield a promoted precursor; drying the promoted precursor to yield dried catalyst; and calcining the dried catalyst, wherein the catalyst further comprises copper and potassium. A method of preparing a strengthened precipitated iron catalyst comprising: co-precipitating iron, copper, magnesium, and aluminum; washing the precipitate; alkalizing the precipitate; and drying the precipitate to yield a dried catalyst precursor.Type: GrantFiled: August 26, 2008Date of Patent: October 2, 2018Assignee: RES USA, LLCInventors: Belma Demirel, Charles B. Benham, Dan Fraenkel, Richard A. Bley, Jesse W. Taylor, Sara L. Rolfe, Harold A. Wright

Patent number: 8946114Abstract: A method of producing stable ferrous nitrate solution by dissolving iron in nitric acid to form a ferrous nitrate solution and maintaining the solution at a first temperature for a first time period, whereby the Fe(II) content of the ferrous nitrate solution changes by less than about 2% over a second time period. A method of producing stable Fe(II)/Fe(III) nitrate solution comprising ferrous nitrate and ferric nitrate and having a desired ratio of ferrous iron to ferric iron, including obtaining a stable ferrous nitrate solution; dissolving iron in nitric acid to form a ferric nitrate solution; maintaining the ferric nitrate solution at a second temperature for a third time period; and combining amounts of stable ferrous nitrate solution and ferric nitrate solution to produce the stable Fe(II)/Fe(III) nitrate solution. A method of preparing an iron catalyst is also described.Type: GrantFiled: May 29, 2009Date of Patent: February 3, 2015Assignee: Res USA, LLC.Inventors: Pandurang V. Nikrad, Jesse W. Taylor, Richard A. Bley, Danny M. Dubuisson, Sara L. Rolfe, Belma Demirel, Dawid J. Duvenhage, Harold A. Wright

Patent number: 7915193Abstract: A method of activating an iron Fischer-Tropsch catalyst by introducing an inert gas into a reactor comprising a slurry of the catalyst at a first temperature, increasing the reactor temperature from the first temperature to a second temperature at a first ramp rate, wherein the second temperature is in the range of from about 150° C. to 250° C., introducing synthesis gas having a ratio of H2:CO to the reactor at a space velocity, and increasing the reactor temperature from the second temperature to a third temperature at a second ramp rate, wherein the third temperature is in the range of from about 270° C. to 300° C. The iron Fischer-Tropsch catalyst may be a precipitated unsupported iron catalyst, production of which is also provided.Type: GrantFiled: November 18, 2008Date of Patent: March 29, 2011Assignee: Rentech, Inc.Inventors: Belma Demirel, Charles B. Benham, Dan Fraenkel, Richard Bley, Jesse W. Taylor, Bahman Rejai, Sara Rolfe, Harold A. Wright
