Gasification of soy hull pellets was carried out in a pilot-scale fluidized bed gasifier under different operating conditions. The experiments were designed to determine the effect of four operating parameters: biomass loading (10–30 wt.%), temperature (750–950 °C), equivalence ratio (0.2–0.4), and fluidization velocity (2.5–4.0 Uff) of the fluidizing gas, on the quality of syngas produced. The interaction between each operating parameter and how they affect syngas quality were also considered using statistical analysis and optimization done via desirability analysis. The syngas quality and gasification performance were measured with respect to the H2:CO ratio, gas yield, carbon conversion, and the cold gas efficiency. The hydrodynamics of the fluidized bed binary mixture at the operating conditions and how the syngas quality was affected were also discussed. Temperature showed the maximum significant effect on the syngas quality with the higher temperature favoring higher H2:CO ratio values as well as gas compositions. High loading of up to 30% in the binary mixture of the fluidized bed was successfully achieved due to the modified nature of the biomass, resulting in higher gas yields. Higher temperatures resulted in higher gas yield and carbon conversion while increasing the equivalence ratio led to lower cold gas efficiency. Gas yields of ~ 4 m3/kg and carbon conversion of ~ 90% were achieved from different combinations of the operating parameters. [ABSTRACT FROM AUTHOR] |
