Analysis of synthesis gas produced from biomass gasification

Abstract

The biomass gasification has been carried out using a fluidized bed gasifier. This work focuses on the production and analysis of syngas from biomass. In the present work four samples namely, rice husk, wood chips , sugarcane bagasse and coconut coir have been studied. The effect of different system parameters viz. temperature, steam to biomass ratio and equivalence ratio on syngas composition has been studied. It is found that with the increase in temperature (from 500 to 800C) within the fluidized bed gasifier hydrogen percentage increases continuously while other parameters are held constant. It is observed that with the increase in steam to biomass ratio yield of hydrogen increases while equivalence ratio (ER=0.25) and temperature of fluidized bed are fixed. Similarly effect of equivalence ratio is studied by keeping other two parameters constant.
