Catalytic Conversion of Municipal Waste into Clean Energy: Optimizing Hydrogen and Syngas Production with Acid-Functionalized Bottom Ash
Keywords:
Municipal solid waste, Gasification, Syngas, Hydrogen, Incineration ashAbstract
Municipal Solid Waste (MSW) management presents a critical environmental challenge. This study investigates a transformative approach: the catalytic steam gasification of MSW using acid-functionalized bottom ash. Employing Response Surface Methodology (RSM) within a modified TG-MS setup enriched with steam, we meticulously analyze key parameters, including temperature, particle size, and catalyst content. Temperature proves the most influential factor in hydrogen and syngas production, revealing a crucial avenue for efficiency enhancement. Acid-treated incineration ash, with active sites and the SO3H functional group, exhibits remarkable catalytic prowess, promising sustainable waste-to-energy conversion. Through rigorous experimentation, we establish optimal conditions for hydrogen and syngas yields: 684°C temperature, 0.84 mm particle size, and 0.65 wt% catalyst content. This parametric study advances our understanding of MSW gasification and offers a promising route to sustainable energy generation from waste. Our research underscores the pivotal role of catalysis in waste management, addressing environmental concerns while unlocking the latent energy within municipal waste. The outcomes have profound implications for sustainable fuel production, emission control, and our broader mission to create a greener, more energy-efficient future. This study pioneers a sustainable approach to MSW management, demonstrating the potential to transform waste into valuable energy resources, contribute to emission control, and shape a more sustainable future.
