Project
Project code: 22010718
Contract period: 01.05.2019

Budget: 333,446 Euro
Purpose of research: Experimental development
Keywords: renewable ressources, inulin, PEF
In light of diminishing fossil resources, plastics like polyesters and polyamides based on renewable resources are a promising alternative to conventional, oil-based polymers. Their great potential is increasingly recognized by a growing number of plastic producers and entails appropriate R&D activities. A promising starting material for the production of bio-based polymers is 2,5-furandicarboxylic acid (FDCA), which can be obtained from carbohydrates and carbohydrate-containing biomass, respectively. Polymers that can be made from it, like the polyester polyethylene furanoate (PEF), are characterized not only by their sustainability, but also by improved properties, like a reduced permeability for oxygen, carbon dioxide and moisture. The aim of the research project "KEFIP” is the development of a sustainable, multistage process for the conversion of inulin-containing chicory roots, an agricultural residue, into FDCA. For that purpose, the inulin, being synthesised during growing and forcing, is firstly extracted, converted into 5-hydroxymethylfurfural by means of hydrothermal dehydration, and finally oxidized to FDCA by bio- and heterogeneous catalysts, respectively. In the sense of a resource-efficient process, HMF originating from the hydrothermal dehydration will not be extracted and purified, but instead it will be directly used for the oxidation. The central process step of this subproject is the catalytic oxidation of HMF to FDCA in the solvent water and with air as the oxidant. For this, robust heterogeneous catalysts, which are also active under neutral or acidic conditions and as tolerant as possible against impurities present in the feed stream, will be developed and tested. This would improve current processes significantly.
