Abstract
Gasification is a promising clean energy technology for hydrogen production and sustainable waste management. Biomass residues have great potential to produce renewable hydrogen. In this study, the potential of production of hydrogen from pepper residues was determined via a modeling study of air/steam gasification system. The input carbon of the feedstock was assumed to be fully gasified in the numerical model calculations performed for the downdraft gasifier system. Air to fuel ratio (A/F) and steam to fuel (S/F) ratio are taken as 0.05 because of the high oxygen content in pepper waste. The temperature of the gasifier is 877 °C for the developed mathematical model. The modeling study results revealed high hydrogen content in the producer gas derived from pepper waste gasification which has obtained as 49.08 %.
