Abstract
Waste generation is a critical problem faced by people in urban areas. Waste can be ultilized as renewable energy through a thermochemical process, namely gasification. This study analyzes the potential of syngas produced from the municipal solid waste gasification process with a mixture of coconut shells as biomass. Using a thermodynamic equilibrium model, gasification parameters such as gasification temperature, composition of the biomass mixture, steam to biomass ratio (SBR), syngas composition, H2/CO ratio and CO/CO2 ratio were analyzed. The model is validated with experimental data and previous research simulations. The results of the simulations carried out using water vapor as a gaseous agent show that the optimal conditions for this biomass gasification are at a temperature of 600 – 750 ° C, and an SBR of 0.6 – 1.2. The use of water vapor as an agent gas can increase the yield of the H2/CO ratio, which is more than 3 and can even reach 8. The synergy between municipal solid waste and coconut shells does not occur in this simulation. This is because in the simulation it is shown that there is a deviation by shifting the Water Gas Shift Reaction to the left.

| Additional Information: | Timbulan sampah merupakan permasalahan genting yang dihadapi masyarakat diwilayah perkotaan. Sampah dapat dimanfaatkan sebagai energi terbarukan melalui proses termokimia, yakni gasifikasi. Penelitian ini menganalisis potensi syngas yang dihasilkan dari proses gasifikasi municipal solid waste dengan campuran tempurung kelapa sebagai biomassa. Dengan menggunakan model kesetimbangan termodinamika, dianalisis parameter gasifikasi seperti temperatur gasifikasi, komposisi campuran biomassa, rasio uap terhadap biomassa (SBR), komposisi syngas, rasio H2/CO dan rasio CO/CO2. Model divalidasi dengan data eksperimen dan simulasi penelitian terdahulu. Hasil simulasi yang dilakukan menggunakan uap air sebagai agen gas menunjukan bahwa kondisi optimal pada gasifikasi biomassa ini adalah pada temperatur 600 – 750 ° C, dan SBR sebesar 0,6 – 1,2. Penggunaan uap air sebagai gas agen dapat meningkatkan hasil rasio H2/CO yakni melebih 3 bahkan dapat mencapai 8. Sinergitas antara municipal solid waste dan tempurung kelapa tidak terjadi dalam simulasi ini. Hal ini karena dalam simulasi diperlihatkan adanya penyimpangan dengan bergesernya reaksi Water Gas Shift Reaction kearah kiri. | |||||||||
