  • Patent number: 9770698
    Abstract: This specification discloses an operational continuous process to convert lignin as found in ligno-cellulosic biomass before or after converting at least some of the carbohydrates. The continuous process has been demonstrated to create a slurry comprised of lignin, raise the slurry comprised of lignin to ultra-high pressure, deoxygenate the lignin in a lignin conversion reactor over a catalyst which is not a fixed bed without producing char. The conversion products of the carbohydrates or lignin can be further processed into polyester intermediates for use in polyester preforms and bottles.
    Type: Grant

  • Patent number: 9718742
    Abstract: This specification discloses a process to convert a converted lignin feedstream to an aromatic composition comprised of aromatic compounds. The process follows the steps of exposing the converted lignin feedstream to at least one catalyst in the presence of donated hydrogen atoms at an exposure temperature greater than 190° C. for a time of at least thirty minutes. The donated hydrogen atoms are donated from at least one hydrogen donating compound during exposure of the converted lignin feedstream to the at least one catalyst at the exposure temperature. The resulting products are comprised largely of aromatics.

  • Patent number: 9340468
    Abstract: This specification discloses an operational continuous process to convert lignin as found in ligno-cellulosic biomass before or after converting at least some of the carbohydrates. The continuous process has been demonstrated to create a slurry comprised of lignin, raise the slurry comprised of lignin to ultra-high pressure, deoxygenate the lignin in a lignin conversion reactor over a catalyst which is not a fixed bed without producing char. The continuous process further utilizes nanoparticles of a crystalline metal oxide. The conversion products of the carbohydrates or lignin can be further processed into polyester intermediates for use in polyester preforms and bottles.

  • Publication number: 20160068456
    Abstract: This specification discloses a complete method to manufacture polyester articles from freshly harvested ligno-cellulosic biomass. The process steps include pretreating the biomass and the converting the lignin to one of several possible organic steams by deoxygenating and dehydrogenating the lignin in the presence of a Raney Nickel catalyst, separating the organics, and then processing the organics into polyester feedstocks and converting those feedstocks to polyester.

  • Publication number: 20150337214
    Abstract: This specification discloses a method to convert a lignin biomass feedstream to a converted lignin stream comprising aromatic compounds. The process comprises combining a lignin biomass feedstream comprising lignin, at least one solvent and at least one catalyst in a reaction vessel. Preferably the ratio of moles of catalyst to moles of lignin is in the range of between 4:1 and 15:1. The lignin biomass feedstream is then deoxygenated to a converted lignin stream at a deoxygenation temperature and a deoxygenation pressure for a deoxygenation time.
