Experimental Study of CO2 Gasification of Biomethanation Waste

Gasification is one of prominent thermochemical processes generally used to convert organic feedstock to combustible syngas (CO and H 2 ).An experimental study of biomass gasification using carbon dioxide as an gasifying medium was carried out in a fixed bed gasifier.The main aim of this study was to determine the effect of temperature on the output syngas.The present study reported the results for producing syngas with CO 2 as gasification agent and biomass (rice husk and bio-methanation waste) as raw material.The gasification was performed at 700-900°C respectively and CO 2 flow rate was maintained at 0.5 lpm.Maximum syngas production found at high temperature (900°C).The syngas analysis showed higher hydrogen yield at higher temperatures.
