Abstract
The objective of this research was to investigate the effects of operating parameters on syngas quality and process performance metrics during the co-gasification of refuse-derived fuel (RDF) and tire waste (TW). This was modeled using simulations by Aspen Plus v10. The influence of gasification temperature, steam flow rate, and air flow rate on syngas composition, lower heating value (LHV), cold gas efficiency (CGE), and syngas yield were thoroughly evaluated. Simulation results revealed an optimal temperature of 700 °C, combined with 0.5 kg/h steam and 0.5 kg/h air flow rates, maximizing the LHV at 17.62 MJ/kg (approximately 14.5 MJ/Nm3), CGE at 75.38 %, and the weight of syngas at 1.28 kg/kg. The optimized conditions facilitated a balanced formation of combustible gases while minimizing carbon losses, generating a high-quality syngas with desirable properties from the co-gasification of RDF and TW.
