Descrizione del progetto
Un nuovo modo per trasformare i rifiuti in prodotti di valore
I rifiuti biogenici possono essere convertiti in prodotti utili come combustibili e sostanze chimiche. Finanziato dal Consiglio europeo della ricerca, il progetto BioValCat mira a rivoluzionare questo processo. Utilizzando materie prime rinnovabili, come la materia prima vegetale e gli scarti agricoli, convertirà i rifiuti biogenici in carburanti e prodotti chimici, riducendo al contempo l’impatto ambientale. Basandosi sulla recente scoperta che i catalizzatori poliossometallati (POM) possono essere manipolati per aumentare l’efficienza e la resa, il progetto mira a sviluppare un processo scalabile, sicuro ed economico per l’ossidazione della biomassa in preziosi esteri di acidi carbossilici. Utilizzando il metanolo come (co)solvente, i catalizzatori POM sopprimono l’inopportuna ossidazione totale a CO2 in condizioni ossidative. BioValCat ha il potenziale per creare un’economia circolare e contribuire a un futuro più sostenibile.
Obiettivo
This project builds on a recent and ground-breaking discovery of the PI in the field of homogeneously catalysed, selective biomass valorisation. Materials technologies that promise improved catalytic performance are of utmost interest for a more sustainable chemical industry. Manipulating molecular catalysts like polyoxometalates (POM) in solution by tuning the solvent properties and gas atmospheres introduces a new paradigm in homogeneous-catalysed biomass valorisation technologies.
It has been found that by using methanol as a (co)solvent, POM catalysts can completely suppress undesired total oxidation to CO2 under oxidative conditions. This drastically enhances the carbon efficiency from biomass to close to 100% yield. Remarkably, this manipulating effect could be explained with the formation of a new vanadyl-methanolate-complex in methanol-aqueous solutions having a methanol content of at least 10%.
The proposed BioValCat project aims for developing this potentially disruptive technology towards an industrial viable biomass valorisation process by laying the foundations for a scalable, safe and economic process for the oxidation of biomass to valuable carboxylic acid esters. The project is structured according to the key challenges that have to be mastered in order to achieve this ambitious goal: a) Investigations to identify the nature of the POM-solvent interactions; b) Understanding and revealing the key organic mechanisms in solution; c) Development of novel POM catalysts specifically optimised to perform in aqueous-alcoholic solvent mixtures; d) Extension of the substrate and product scope to industrially viable biomass feedstock; e) Process development, with special emphasis on safety aspects, process intensification as well as product isolation and catalyst recovery.
With the proposed project the PI aims for paving the scientific route to novel, low-cost biomass utilisation technologies with great promise for decentralised valorisation of biogenic waste.
