Publication number: 20140135470Abstract: 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.Type: ApplicationFiled: June 15, 2012Publication date: May 15, 2014Applicant: CHEMTEX ITALIA, S.p.A.Inventors: Aaron Murray, Steven Ryba

Publication number: 20140096830Abstract: 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: ApplicationFiled: February 24, 2013Publication date: April 10, 2014Applicant: CHEMTEX ITALIA, S.P.A.Inventor: CHEMTEX ITALIA, S.P.A.

Publication number: 20130256323Abstract: This specification discloses a composition of a melt blend comprising a continuos polyester phase, a cobalt of manganese compound and a first scavenging compound wherein the first scavenging compound comprises at least one allylic group and at least one polar moiety and at least some of the first scavenging compound or the oligomer or the polymer comprising the first scavenging compound is not present in the continuous polyester phase. The partial insolubility is essential for oxygen scavenging and the solubility is essential for reducing haze. The composition is useful in preforms, container walls, and films for packaging.Type: ApplicationFiled: April 1, 2013Publication date: October 3, 2013Applicant: Chemtex Italia, S.p.A.Inventors: Ricardo Knudsen, D.
