概要 This study addresses the urgent matter of municipal solid waste (MSW) management by exploring its potential conversion into renewable energy through thermochemical processes. Specifically, the researc...h investigates the generation of synthesis gas (syngas) through the gasification process of municipal solid waste, incorporating a biomass blend with coconut shells. Employing a validated thermodynamic equilibrium model, various gasification parameters such as temperature, the composition of biomass, the steam-to-biomass ratio (SBR), the composition of the resulting syngas, the ratio of hydrogen to carbon monoxide (H_2/CO), and the ratio of carbon monoxide to carbon dioxide (CO/CO_2) were analyzed. The model underwent rigorous validation through comparison with experimental data and simulations from prior research. Simulation outcomes, utilizing steam as the gasifying agent, identified optimal conditions for biomass gasification within the temperature range specified is between 600 and 750°C and an SBR of 0.6 – 1.2. Notably, steam gasification led to an enhancement in the H_2/CO ratio, exceeding 3. However, the simulation revealed a lack of compatibility between municipal solid waste and coconut shells, attributed to deviations in the Water Gas Shift Reaction, which skewed leftward. These findings offer significant insights into the complexities and potentials of sustainable waste-to-energy endeavors.続きを見る
