Gasification is one of the most promising technologies for converting biomass into a fuel. The main objective of this research is to study the effect of design and operating parameters, mainly as Bed Temperature (T), Pressure (P), Equivalence Ratio (ER), Feed rate (F) and Particle Size (S) on the performance of the gasification process of coconut shell as biomass in a continuous fixed bed updraft reactor. In the present investigation, an empirical relationship was developed to predict the process of generating fuel gas with better quality through gasification of biomass in a fluidized bed reactor using Response Surface Methodology (RSM). Six major components of the producer gas such as O2, H2, CO, CO2, CH4, and N2 are analyzed in the laboratory along with the evaluation of tar yield and cold gas efficiency. It was observed that the concentrations of Hydrogen, Oxygen Nitrogen and Carbon monoxide were increased with rise in Gasification Temperature, Pressure and Equivalent Ratio (0.2-0.35). On the other hand, higher Equivalence Ratio (0.4-0.5) caused to decrease the concentrations of Hydrogen, Oxygen, Nitrogen and Carbon Monoxide. The developed model was made a good prediction for the experimental data as observed for the gas species concentrations.
