Description du projet
Une voie durable pour la production du FDCA
L’acide 2,5-furandicarboxylique (FDCA), un composé chimique organique, offre des possibilités intéressantes pour créer une grande variété de polymères, notamment des polyesters, des polyamides et des polyuréthanes. Il peut être utilisé pour remplacer les monomères à base de pétrole que sont l’acide téréphtalique et l’acide adipique. Le projet Cell2Carbox, financé par l’UE, vise à rendre la production du FDCA moins coûteuse et plus écologique. Il utilisera comme matière de base la biomasse cellulosique, qui est la matière première la plus abondante sur Terre. Des catalyseurs à atome unique seront utilisés pour la conversion de la biomasse. Cette approche catalytique offre une solution prometteuse pour améliorer le processus de conversion chimique traditionnel et en diminuer le coût. En outre, par rapport aux catalyseurs traditionnels, le catalyseur à atome unique se caractérise par une activité, une sélectivité et une stabilité supérieures.
Objectif
Furan-2,5-dicarboxylic acid (FDCA) is a biobased product and an important chemical building block. It has a huge potential as a substitute for a variety of petrochemicals, such as terephthalic acid and adipic acid. It is highly important for the pharma industry as it is being used in biopolymer industries to make polyesters, polyurethanes, and polyamides. Currently, avantium process is the only established industrial process consisting of the catalytic dehydration of carbohydrates to alkoxymethylfurfural (RMF) which is further oxidized to the sodium salt of FDCA using homogenous catalytic system. Using the homogeneous catalytic system for oxidation process followed by the alkaline solution for separation process makes the process more expensive and less eco-friendly. However, base-free systems lead to low yield and selectivity, therefore extensive research is required for exploring a new heterogenous catalytic system. Direct utilization of cellulosic biomass as a feedstock over the multifunctional heterogeneous catalytic system will improve the economic feasibility with optimized production technologies, as these are abundantly available at a low cost. I will achieve this goal by designing a multifunctional catalyst with the combined effect of acid, base and metal sites as a single atomic site. Cell2Carbox project aims to develop unique and sustainable catalytic processes for FDCA production from an inexpensive and highly abundant cellulosic biomass using multifunctional heterogeneous SACs (Single-atom based catalyst) system. Besides, the project comprises a program for my professional growth by training-through-research in heterogeneous catalysis and for the development of complementary skills. Strengthened by this experience, I will become independent expert in the process development for biomass valorization, as of major scientific importance in the coming decades as it is postulated in the EU Vision The circular bio-society in 2050.
