Patent number: 9163185Abstract: The invention provides methods and apparatus ultimately for converting a carbonaceous material to liquid hydrocarbons suitable for use, for example, as transportation fuels. In a first step the carbonaceous material is converted to a syngas product, and in subsequent steps the syngas product is converted to the desired liquid hydrocarbons. In one embodiment, coal and methane are converted to syngas, and the syngas product is converted to hydrocarbons through a methanol intermediate. An example use for the methods and apparatus of the invention is in the preparation of aviation fuels.Type: GrantFiled: August 28, 2013Date of Patent: October 20, 2015Assignee: SRI INTERNATIONALInventors: Daniel Steele, Robert B. Wilson, Ripudaman Malhotra, Brian Adair

Publication number: 20090032468Abstract: This invention is directed to systems and methods for removing lipids from a fluid, such as plasma, or from lipid-containing organisms. These systems contact a fluid with an extraction solvent, which causes the lipids in the fluid to separate from the fluid or causes lipids in the lipid-containing organisms to separate from the lipid-containing organism, using at least one hollow fiber contactor. The separated lipids are removed from the fluid. The extraction solvent is removed from the fluid or at least reduced to a level below a particular threshold enabling the fluid to be administered to a patient without the patient experiencing undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid, to a different patient, or be stored.Type: ApplicationFiled: October 8, 2007Publication date: February 5, 2009Applicant: Lipid Sciences, Inc.Inventors: David C. Bomberger, Pablo E. Garcia, Eric Hegwer, Thomas P. Low, Ripudaman Malhotra

Publication number: 20080203022Abstract: This invention is directed to systems and methods for removing lipids from a fluid or from lipid-containing organisms from a fluid, such as plasma. These systems combine a fluid with at least one extraction solvent, which causes the lipids to separate from the fluid or from the lipid-containing organisms. The separated lipids are removed from the fluid. The at least one extraction solvent is removed from the fluid or at least reduced to a concentration enabling the fluid to be administered to a patient without undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid or to a different patient for therapy.Type: ApplicationFiled: May 5, 2008Publication date: August 28, 2008Applicant: Lipid Sciences, Inc.Inventors: David C. Bomberger, Bryan Chavez, Pablo E. Garcia, Eric Hegwer, Thomas P. Low, Ripudaman Malhotra, Jeffrey J. Shimon

Publication number: 20080083671Abstract: Systems and methods for removing lipids from a fluid, such as plasma, or from lipid-containing organisms. A fluid is combined with at least one extraction solvent, which causes the lipids to separate from the fluid or from lipid-containing organisms. The separated lipids are removed from the fluid. The extraction solvent is removed from the fluid or at least reduced to an acceptable concentration enabling the delipidated fluid to be administered to a patient without the patient experiencing undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid, to a different patient, or stored for later use.Type: ApplicationFiled: October 8, 2007Publication date: April 10, 2008Applicant: Lipid Sciences, Inc.Inventors: David Bomberger, Bryan Chavez, Pablo Garcia, Eric Hegwer, Thomas Low, Ripudaman Malhotra, Jeffrey Shimon
