Description du projet
Un concept de bioraffinerie qui améliore l’efficacité de la purification et de la conversion des sucres
La lignocellulose est la biomasse la plus disponible au monde. Elle revêt une importance particulière pour la bioéconomie, notamment dans le cadre de la production de produits chimiques et de matériaux d’origine biologique. Actuellement, les inefficacités observées dans les procédés entrainent des coûts élevés en matière d’énergie et d’utilisation des ressources. Le projet BioSPRINT, financé par l’UE, entend développer et valider des méthodes d’intensification des processus afin d’améliorer la purification et la conversion de la fraction hémicellulosique de la biomasse lignocellulosique comme le bois dur et la paille. Leur transformation en nouvelles résines d’origine biologique serait ainsi réalisable et il deviendrait possible de les substituer aux polymères d’origine fossile. BioSPRINT se concentrera sur quatre domaines d’activité: la purification en amont, la conversion catalytique, la purification en aval et la polymérisation. En axant ses travaux sur des technologies permettant d’intensifier les méthodes de traitement et en adoptant un concept de bioraffinage intégré, le projet a pour objectif de parvenir à des opérations de bioraffinage «zéro déchet», ce qui permettra d’accroitre l’efficacité et donc de réduire la consommation de ressources énergétiques et de limiter les émissions de gaz à effet de serre.
Objectif
Building on successful projects and relevant assets from partners and an interdisciplinary approach, BioSPRINT applies process intensification in the context of biorefining operations, so as to improve the efficiency of the purification and conversion of sugars from the hemicelluloses fraction of lignocellulosic biomass and to enable their transformation into new bio-based resins for substituting fossil based polymers in a range of applications. The ultimate objective is to lead to a reduction in operation costs, feedstock and energy resources, greenhouse gas emissions and higher yields, while increasing operation safety, by concentrating on technologies which can intensify processing methods and create an integrated biorefinery concept. Of particular interest in BioSPRINT is the valorisation of hemicelluloses streams derived from hard wood and straw, from processes employed in the production of paper pulp or biofuels. Such streams are readily available from the pilot or production processes of the project’s research and industrial partners (Fraunhofer and UPM). A case study using a stream from Clariant will also be carried out. With regards to processing technologies, BioSPRINT will focus on 4 activity areas (a) Upstream purification; (b) Catalytic conversion; (c) Downstream purification and (d) Polymerisation. The project will develop and validate an intensified and integrated purification strategy leveraging innovative anti-solvent precipitation and membrane separation methods, novel intensified and integrated catalytic processes for dehydration of C5 and C6 hemicelluloses sugars into monomers, extractive-reaction methods to isolate the reaction products from the reaction medium in situ, heterogeneous catalysts and an intensified polymerisation process for furan-based derivatives. Cross-cutting activities will cover process simulation and optimisation, an integrated Lifecycle sustainability assessment, standardisation, dissemination and exploitation activities
