Patent number: 11781077Abstract: Described is a novel process for disaggregating biomass pyrolysis oil quantitatively into energy dense hydrophobic aromatic fraction (HAF), fermentable pyrolytic sugars and phenolics based products in a highly economical and energy efficient manner. Phase separation of the esterified pyrolysis oil after an oxidative pre-treatment and the quantitative recovery of the separate fractions is described. Phase separation uses batch as well as continuous reactor systems. The resulting HAF is an energy dense, thermally stable, water free, non-corrosive to carbon steel, and is a free flowing liquid suitable for combustion and for upgrading to transportation fuels. Pyrolytic sugars which are mainly anhydrosugars can be further converted by fermentation to ethanol or other products. Monomeric phenols are useful industrial intermediates and the organic acids in the original pyrolysis oil are mainly recovered as esters of the separation solvents.Type: GrantFiled: February 9, 2022Date of Patent: October 10, 2023Assignee: ALDER ENERGY, LLCInventors: Sanjeev Gajjela, Ralph Phillips Overend, Zhiheng Wu, Zsuzsa Ajsa Mayer, Haonan Wu, Jose Antonio Medrano Catalan

Publication number: 20230049368Abstract: Described is a novel process for fractionating biomass pyrolysis oil quantitatively into energy dense hydrophobic aromatic fraction and water-soluble organics in an economical and energy efficient manner. Using the concepts of solvents and anti-solvent behaviors to separate the pyrolysis oil, which is an emulsion, a method utilizing minimal quantities of solvents and water is proposed, by comparison with the existing methods to isolate the hydrophobic aromatic fraction, there is a volume reduction of greater than 50:1. Additionally, there is a significant time saving over the 24 hours for the accepted method as a solvent, and the anti-solvent system is spontaneous.Type: ApplicationFiled: September 14, 2022Publication date: February 16, 2023Inventors: Sanjeev Gajjela, Ralph Phillips Overend, Javier Gonzalez Catalan, Zhiheng Wu, Patricia LaPuente, Jose Antonio Medrano Catalan
