Abstract

In recent years renewable energy resources are identified for power generation to solve the energy crisis and reduce the emission level. Among renewable energy resources, biomass is abundantly available on earth, huge potential as a feedstock for the bioenergy power generation. In this proposed study, a comprehensive characterization of cashew nutshell biomass is to be performed. The downdraft gasifier is used to generate power from biomass. Cashew nutshell has an energy content of 20.42 MJ/kg. Direct combustion of cashew nutshell leads to smoke emission. Hence feasibility study of cashew nutshell will be performed to check whether it can be potential fuel for downdraft gasification. Results from elemental composition, thermal studies, and calorific value studies revealed that cashew nutshell can be used as feedstock for downdraft gasifier. The syngas obtained from cashew nutshell contains the gas composition of hydrogen 18.25% and carbon monoxide 13.83%
