Integration of carbon materials morphology and properties into detailed kinetic models for carbon deposit valorization

Objective

Industrial processes key to the green transition, such as biomass and waste pyrolysis or turquoise hydrogen production, unavoidably generate solid carbon materials. Traditionally, these carbon deposits (CDs) reduce reactor efficiency, and these carbon nanoparticles (CNPs) contribute to harmful emissions. Yet, recent findings reveal that similar products from hydrocarbon pyrolysis can exhibit exceptional optical, electronic, and mechanical properties, akin to advanced carbon nanomaterials. Harnessing these properties could transform CDs and CNPs from costly by-products into value-added carbons (VACs), boosting the economic viability of sustainable technologies. Despite this potential, no current model links operating conditions to the morphology and functional properties of carbon materials. Existing approaches are descriptive, system-specific, and unsuitable for industrial design. KINMECPRO will close this critical gap by developing the first kinetic model that connects chemical mechanisms, structure formation and carbon material properties. To achieve this, the project combines: molecular dynamics simulations to generate surrogate structures and key morphological descriptors; quantum chemistry methods to calculate electronic and optical properties; and shock tube reactor experiments to provide high-quality data at well-defined conditions. The resulting one-of-a-kind predictive model will guide the design and scale-up of innovative pyrolysis processes, minimizing waste while maximizing the production of VACs. Scientifically, it will establish a new framework for linking chemical kinetics to solid-state material properties. Societally, it will enable cleaner energy systems and circular use of resources, supporting the European Green Deal and UN SDGs. For the researcher, it represents a unique opportunity to acquire interdisciplinary expertise and leadership skills, laying the foundation for an independent career at the frontier of sustainable chemistry and materials.
