Abstract


This study investigates the co-gasification of municipal solid waste (MSW) and coconut shell (CS) using natural zeolite catalysts, with a focus on elucidating physicochemical properties, syngas composition, and potential synergistic effects to enhance energy production performance. Proximate and ultimate analyses of MSW and CS delineate distinctive properties, guiding optimized co-processing. Natural zeolite catalysts, identified as mordenite, clinoptilolite, and alpha quartz via XRD analysis, introduce a novel dimension with potential catalytic influences on gasification products. Experimental assessments reveal the nuanced impact of varying biomass ratios on syngas composition, showcasing significant shifts in CO, CH₄, and H₂ concentrations quantified through gas chromatography. Flame color visualizations, captured quantitatively in real-time, provide immediate indicators of flammable gas presence during co-gasification scenarios, offering insights into process dynamics. Residue analyses, quantified across different biomass ratios, delineate tar, char, and gas distributions, informing optimization strategies. XRD analysis of chars at 750°C quantitatively illustrates microcrystalline structures and potential catalytic implications of CaCO₃ in the presence of MSW. This study bridges theoretical and practical dimensions, providing quantitative insights into the gasification process, syngas composition, and residue management. Emphasizing the potential of co-gasification with natural zeolite catalysts, it contributes substantial quantitative data, positioning itself as a scientific reference for advancing waste-to-energy processes and optimizing biomass utilization. The study underscores the importance of synergistic effects in achieving enhanced performance and sustainability in waste-to-energy conversion.
