Development of a Green Catalytic Process for Biomass-Derived Platform Chemicals via Heterogeneous Catalysis and Process Simulation

Project Abstract

This research presents the development and validation of a green catalytic process to efficiently convert biomass-derived platform chemicals into high-value end products using heterogeneous catalysis and process simulation. The study integrates catalyst design, reaction engineering, and digital twin modeling to achieve superior sustainability metrics, including reduced energy consumption, minimized waste generation, and lower carbon footprint. The catalyst system comprises earth-abundant metals supported on mesoporous oxides, engineered to exhibit high activity, selectivity, and resistance to deactivation under biomass-derived feedstock conditions. Through systematic screening, key parameters such as metal loading, particle size, support acidity/basicity, and textural properties were correlated with catalytic performance in transformative reactions (e.g., dehydration, hydrogenation, oxidation) relevant to platform chemicals like levulinic acid derivatives, hydroxymethylfurfural (HMF) products, and furfural pathways. A multidisciplinary methodology was employed, combining spectroscopic characterization (XRD, BET, TEM, XPS, CO2-TPD), in-situ/reactive spectroscopy, and kinetic experiments to elucidate active sites and mechanism. Process simulation was implemented using rigorous steady-state and dynamic models to optimize reactor configurations, heat integration schemes, and separation trains. The simulations were calibrated with experimental data to predict yields, selectivity, and energy consumption under varying biomass feed compositions and pretreatment steps. Lifecycle assessment (LCA) and techno-economic analysis (TEA) were conducted to quantify environmental and economic viability, informing trade-offs between catalyst cost, lifetime, and process intensification opportunities. Key findings demonstrate that a tailored bifunctional catalyst can efficiently convert biomass-derived platform molecules to value-added chemicals with high selectivity under mild conditions, enabling significant reductions in pressure, temperature, and solvent use compared with conventional pathways. The process flow integrates pretreatment steps that minimize oxygenates and inorganic impurities, followed by catalytic conversion in a continuous-flow reactor with optimized residence times. Heat integration strategies and solvent recycling loops contribute to substantial energy savings and waste minimization. The digital twin model provides real-time control strategies for reactor-operating windows, enabling rapid scenario analysis for scale-up and retrofit of biorefineries. Sensitivity analyses identify critical variables such as feedstock composition, catalyst aging, and separator efficiency, informing robust design margins. The outcome demonstrates that the proposed green catalytic route can outperform traditional petrochemical analogs in environmental indicators while maintaining competitive economics under realistic market scenarios. This work advances fundamental understanding of structure–activity relationships in biomass-compatible heterogeneous catalysts and delivers a scalable, renewable-based chemical production platform. The integrated framework offers a blueprint for deploying green catalysis in industrial settings, aligning with circular economy principles and policy-driven sustainability targets. The project provides actionable guidelines for catalyst synthesis, reactor design, process integration, and digital optimization to accelerate the adoption of biomass-derived platform chemicals in high-value applications.
