Intrinsic and extrinsic analysis of the elemental composition of biomass to enrich the quality of producer gas: Thermodynamic equilibrium model-based investigation

Gasification is a promising technology for the conversion of renewable resources such as biomass into gaseous fuel while offering low emissions. In this research study, the stoichiometric equilibrium model is used to predict gas composition and optimize gasification parameters. The analysis reveals that biomass, like pine needles, has higher moisture (19.53%) and higher fixed carbon content (21.37%), which increases the methane concentration and gas production rate by 48.7% and 45.3%, respectively, and reduces the carbon dioxide fraction by 46.3%. High-volatile-content biomass-like bagasse increases carbon monoxide and hydrogen concentrations by 55.5% and 10.3%, respectively. High ash and oxygen content biomass, such as beef cattle manure and groundnut shell, increase the gas production rate by 58.5% and 15.2%, respectively. High hydrogen content, like palm empty fruit bunch, produces a higher gas heating value of 10.96 MJ/m3.
