Patent number: 9770698Abstract: 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: GrantFiled: August 13, 2015Date of Patent: September 26, 2017Assignee: Biochemtex S.p.A.Inventors: Dan Gastaldo, Steven Ryba, Aaron Murray, Guliz Arf Elliott

Patent number: 9340468Abstract: 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.Type: GrantFiled: July 9, 2013Date of Patent: May 17, 2016Assignee: Biochemtex S.p.A.Inventors: Krishna Sharma, Aaron Murray, Steven Ryba, Dan Gastaldo, Guliz Arf Elliott

Patent number: 8231937Abstract: Compartmentalized chips of at least two chemically similar crystallizable thermoplastic polymers each having a different intrinsic viscosity placed in separate zones are disclosed. These compartmentalized chips exhibit thermal characteristics that are different from the traditional technique of homogeneously combining the two materials into the chip. These compartmentalized chips in their amorphous, crystalline and solid phase polymerized forms exhibit a longer crystallization half time than the homogeneous mixture, thus permitting faster injection cycle times when compared to an equivalent homogenous mixture.Type: GrantFiled: July 8, 2011Date of Patent: July 31, 2012Assignee: M&G USA CorporationInventors: Delane Nagel Richardson, Edwin A. Sisson, Gianluca Ferrari, Dan Gastaldo, Freddie L. Massey
