Patent number: 10392317Abstract: The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose, starch, sugar) and ethylene in the presence of a catalyst. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF), which may be converted into para-xylene by cycloaddition of ethylene to DMF. Para-xylene can then be oxidized to form terephthalic acid.Type: GrantFiled: September 13, 2013Date of Patent: August 27, 2019Assignee: MICROMIDAS, INC.Inventors: Makoto N. Masuno, Ryan L. Smith, John Bissell, II, Patrick B. Smith, Dennis A. Hucul, Edmund J. Stark, Daniel R. Henton, Adina Dumitrascu, Katherine Brune, Dimitri A. Hirsch-Weil

Patent number: 9890101Abstract: The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose) and ethylene in the presence of an acid, such as a Lewis acid. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF) and 2-methylfuran, which may be converted into para-xylene and toluene, respectively. In particular, para-xylene can then be oxidized to form terephthalic acid.Type: GrantFiled: January 12, 2016Date of Patent: February 13, 2018Assignee: MICROMIDAS, INC.Inventors: Makoto N.

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
