Green synthesis and catalytic upgrading of biomass-derived platform chemicals into high-value fuels and polymers

Project Abstract

This study presents a holistic approach to converting biomass-derived platform chemicals into high-value fuels and polymers through green synthesis and catalytic upgrading, addressing sustainability, efficiency, and economic feasibility. Biorefineries generate platform molecules such as hydroxymethylfurfural, levulinic acid, levulinic esters, and platform sugars that can be transformed into a broad spectrum of fuels and polymer precursors. The research integrates catalyst design, process intensification, and life cycle considerations to minimize energy input, water use, and greenhouse gas emissions while maximizing product selectivity and yield. Advanced catalytic strategies, including heterogeneous metal catalysts, bifunctional acid–base systems, and cooperative nanostructured materials, are developed to promote selective deoxygenation, hydrodeoxygenation, hydrogenation, and condensation reactions under mild conditions using renewable hydrogen sources or transfer hydrogenation. In parallel, solvent-free or solvent-reduced reaction protocols and the use of benign solvents such as supercritical CO2 or bio-based solvents are explored to reduce environmental impact. The project emphasizes in situ valorization of byproducts and integration with carbon capture or utilization pathways to close material loops. Kinetic modeling and mechanistic elucidation are combined with reactor design optimization, employing microreactor and continuous-flow platforms to enhance heat and mass transfer, safety, and scalability. The research investigates catalyst activation, stability, and recyclability in the presence of bio-derived impurities, and develops regeneration strategies to extend catalyst life. Product performance is evaluated through comprehensive physicochemical characterization, including GC-MS, NMR, FTIR, and rheological analysis, coupled with material property assessments such as cetane number, iodine value, oxidation stability for fuels, and thermal/mechanical properties for polymers. A techno-economic assessment (TEA) and a life cycle assessment (LCA) accompany the process development to quantify profitability, environmental footprint, and social implications, generating benchmarks against conventional fossil-based routes. The study anticipates achieving high selectivity toward targeted fuel fractions (n-alkanes, cycloalkanes) and polymer monomers (e.g., biobased ethylene, propylene derivatives, and polyesters) with competitive energy consumption and reduced catalyst loading. Sensitivity analyses identify critical operational parameters and feedstock variability, guiding feedstock diversification strategies. The anticipated outcomes include a validated, scalable catalytic workflow for upgrading biomass-derived platform chemicals into value-added fuels and polymers, a robust understanding of structure–activity relationships guiding catalyst design, and a framework for industrial integration that aligns with circular economy principles and policy incentives. Potential challenges such as feedstock heterogeneity, catalyst deactivation, and process integration are addressed through adaptive process control, robust catalyst scaffolds, and modular reactor configurations. Overall, the research contributes to the sustainable production of high-value fuels and polymers from renewable resources, offering a viable path toward reducing reliance on non-renewable feedstocks while meeting performance standards and regulatory requirements.
