Publication number: 20220144647Abstract: Provided is a method of producing activated carbon from a resin composite made up of furanic polymer. The method includes producing a resin composite from feedstock (e.g., in the presence of an acid and a salt), combining the resin composite with a base to form an impregnated material, and carbonizing the impregnated material to produce the and salt activated carbon. Provided herein are also resin composites and activated carbon materials.Type: ApplicationFiled: June 14, 2021Publication date: May 12, 2022Applicant: Origin Materials Operating, Inc.Inventors: Ryan L.

Patent number: 10604498Abstract: The present disclosure provides methods for purifying a 5-(halomethyl)furfural composition, including 5-(chloromethyl)furfural, at operating conditions that decrease or minimize the decomposition or degradation of 5-(chloromethyl)furfural during the process. The methods may employ certain solvents, operating conditions, and/or techniques (e.g., gas stripping). The gaseous 5-(halomethyl)furfural produced from the process can be condensed or deposited to yield 5-(halomethyl)furfural in liquid or solid form. The solid 5-(halomethyl)furfural may be amorphous or crystalline.Type: GrantFiled: August 1, 2018Date of Patent: March 31, 2020Assignee: MICROMIDAS, INC.Inventors: Alex B. Wood, Shawn M. Browning, Makoto N. Masuno, Ryan L. Smith, John Bissell, II

Patent number: 9840486Abstract: Provided herein are methods of producing dialkylfurans, such as 2,5-dimethylfuran, and other alkyl furans, such as 2-methylfuran. For example, 2,5-dimethylfuran may be produced by hydrogenation of (5-methylfuran-2-yl) methanol or 2-(chloromethyl)-5-methylfuran in the presence of a solid supported metal catalyst having an excess of either basic or acidic sites (as determined by chemisorption of CO2 or NH3). The process could further include a urea reagent (TMU, DMPU, TMI) and an alkyl benzene.Type: GrantFiled: August 14, 2015Date of Patent: December 12, 2017Assignee: Micromidas, Inc.Inventors: Dennis A. Hucul, Dimitri A. Hirsch-Weil, Makoto Nathanael Masuno, John Albert Bissell, II, Alex B. Wood, Robert Joseph Araiza, Daniel R. Henton, Shawn M. Browning, Ryan L. Smith

Patent number: 9388151Abstract: The present disclosure provides methods to produce 5-(halomethyl)furfural, including 5-(chloromethyl)furfural, by acid-catalyzed conversion of biomass. The methods make use of certain organic solvents with temperature-dependent solubility for 5-(halomethyl)furfural. This allows for temperature-dependent phase separation of the 5-(halomethyl)furfural from the reaction mixture. In certain embodiments, solid 5-(halomethyl)furfural may be obtained. The solid 5-(halomethyl)furfural obtained may be amorphous or crystalline.Type: GrantFiled: October 25, 2013Date of Patent: July 12, 2016Assignee: Micromidas, Inc.Inventors: Shawn M.
