Abstract

In this study, combustible gas production from shell biomass materials such as coconut shell, groundnut shell and rice husk was experimentally investigated at 800⁰ C using gasification technique by a downdraft gasifier. The combustible gases H₂, CO, CH₄, CO₂, and N₂ were formed. The calorific value of the producer gas for various shell materials was found. The calorific value of coconut shell is 23.01% higher than ground nut shell and 45.45% higher than rice husk. Based on performance analysis, it is concluded that coconut shell is the best suitable fuel for gasifier compared to the other two biomass shell materials.
Keywords: Biomass, gasification, coconut shell, groundnut shell, rice husk, energy from waste.
