Beyond Net-Zero Carbon Emissions in Industrial Process through Catalyst-Aided Amine Solvents for the Indirect Co-Combustion of Natural Gas and Biomass

Abstract

This poster demonstrate research efforts undertaken to explore innovative approaches to achieving net-zero carbon emissions in industrial processes by integrating catalyst-enhanced amine solvents for the indirect co-combustion of natural gas and biomass. The research focuses on the development and optimization of heterogeneous solid-base catalysts to enhance CO₂ absorption rates, improve solvent loading, and increase overall process efficiency. Various catalysts, including PEI-modified catalysts, K/MgO, K/MgO-CaO, and activated carbon blends, were synthesized and evaluated. Results indicated significant improvements in CO₂ capture rates, with the K/MgO-CaO catalyst demonstrating notable chemical, thermal, and mechanical stability. Furthermore, a life cycle assessment (LCA) based on the ReCiPe methodology highlighted the environmental benefits of this novel catalyst-solvent system compared to conventional MEA-based carbon capture and the novel solvent AMP:PRLD. This work presents a promising pathway for power and energy sectors to enhance sustainability, reduce emissions, and move beyond net-zero targets.
