Patent number: 10590350Abstract: In various aspects, methods and apparatuses for liquid-liquid extraction are provided. In certain aspects, an emulsion can be formed by combining a feed stream, an extractant, and a surfactant. The feed stream comprises a plurality of distinct components including a first component to be removed therefrom. The feed stream may be selected from a group consisting of: a hydrocarbon feed stream and an azeotrope. Then, a portion of the first component is extracted from the feed stream (or emulsion) by contact with a superoleophobic and hygroscopic membrane filter that facilitates passage of the first component and extractant through the superoleophobic and hygroscopic membrane filter. A purified product is collected having the portion of the first component removed. Such methods are particularly useful for refining fuels and oils and separating azeotropes and other miscible component systems. Energy-efficient, continuous single unit operation apparatuses for conducting such separation techniques are also provided.Type: GrantFiled: January 12, 2018Date of Patent: March 17, 2020Assignees: THE REGENTS OF THE UNIVERSITY OF MICHIGAN, The Government of the United States, as represented by the Secretary of the Air ForceInventors: Josiah T.

Patent number: 10233261Abstract: A method of making natural polymer (nano)particles, comprises two immiscible phases and a surface active agent, wherein one phase includes a natural polymer source and ionic liquid; stirring the combined phases with surfactant to form a microemulsion; adjusting the ratios of ionic liquid, surfactant, and immiscible phase to determine a particular size of natural polymer nanoparticles; stirring antisolvent into the emulsion; diluting the emulsion; and washing and drying precipitated polymer (nano)particles from the emulsion. The immiscible phase comprises at least one of immiscible solvent, oil, or immiscible ionic liquid. The ionic liquid phase includes natural polymer dissolved in ionic solvent. The antisolvent is water, other protic solvent or additive. The emulsion is diluted with, more immiscible phase, 1-butanol, or a mutually miscible solvent, or oil. The emulsion is diluted with an excess of the volume of the emulsion.Type: GrantFiled: August 9, 2017Date of Patent: March 19, 2019Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Jeffrey Alston, Joseph Mabry, Andrew Guenthner

Patent number: 9777161Abstract: Treated, mesoporous aggregates comprising a plurality of coated particles that comprise an inorganic oxide core having a surface area of about 50 to about 500 square meters per gram and a shell or coating consisting of an array of fluoroalkyl molecular chains covalently bonded to the core at a density of at least one chain per square nanometer. The aggregates are formed by the chemical attachment of fluoroalkyl-alkylsilanes after exposure to an alkylamine and followed by an extraction to remove any unbound organic material. The dense packing of molecular chains in the fluoroalkyl shell combined with a mesoporous structure imparts a very low surface energy, a very high specific surface area, and surface texture over a wide range of length scales. Such features are highly desirable for the creation of, for example, superhydrophobic and superoleophobic surfaces, separation media, and release films.Type: GrantFiled: April 18, 2014Date of Patent: October 3, 2017Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Raymond Campos, Andrew Guenthner, Timothy Haddad, Joseph M.
