The aim of the 3DPRINTCAT4BIOMASS project is the development of novel, versatile, and robust catalytic systems applicable to multiple biomass feedstocks.

Due to the advandages of 3D-printing compared to traditional manufacturing technologies, the heterogeneous catalyst will be synthetised by 3D printing process will involve the use both of biopolymer (chitosan) combined with polylactic acid and of metals (Ru, Au, Pt and Fe).

The synthesis of these materials will be monitored by a number of external (ex-situ) characterization techniques including XRD, SEM- and EDX mapping, BET surface area, TEM, XPS, DRIFTs, DRUV, TPD/TPR and surface acid/base group analysis. The conversion of lignocellulosic materials to high added value chemicals and biofuel precursors such as furans, levulinates, γ-valerolactone and valeric esters over 3D printed heterogeneous catalysts will be carry out in autoclave and/or microwave conditions. Optimized reaction conditions in batch (autoclave conditions and/or microwave conditions) will be translated into a continuous flow process using some of our ´in-house´ equipment, in the liquid phase (Phoenix reactor). The aim of these experiments is not only to test the potential scalability of the process, but most importantly, the long-term stability of the catalysts under the present conditions.

The aim of this project is the development of novel, versatile, and robust catalytic systems applicable to multiple biomass feedstocks.

The project aims to fulfill the following objectives:

1. Design and optimisation of 3D printed catalytic systems based on biopolymers/metal nanoparticles, as well as ex situ characterisation for fundamental understanding;


2. Deep and insightful characterisation of all synthesized materials for the work to provide optimisation possibilities and full understanding of the 3D printing step;


3. Understanding of the underlying reactivity of sugars (xylose) and lignin model compounds towards their conversion to valuable chemicals and biofuel precursors in view of the valorisation of analogous compounds from lignocellulosic feedstocks;


4. Integrated full valorisation of two fractions of lignocellulosic residues, aiming to convert hemicelluloses into high added value chemicals and biofuel precursors and lignin into simple aromatic molecules of interest for additives in fuels (gasoline and jet fuels);


5. Analysis of the processes and technologies via Life Cycle Assessment (LCA) and techno-economic analysis of the selected processes to propose at least one feasible for industry;


6. Beginning an unprecedented multidisciplinary 3D printing chemo technological/waste valorisation/environment program in a pioneer research line of top future priority in all world-wide research programs which tackles the waste management problem and environmental solutions for future energy demands.
