Abstract

Biomass energy conversion through thermo chemical conversion process yield producer gas having hydrogen, carbon monoxide and carbon dioxide as major constituents. Air is used as gasifying agent for producer gas generation. In this study proximate analysis was carried out for coir pith and groundnut shell mixture in muffle furnace for fixed carbon determination. Temperature of the reactor  and Gas composition have been analyzed for equivalence ratios of 0.3, 0.4 and 0.5 for 10 minute time interval and its effect on gas constituents has been studied. The maximum temperature attained during gasification process was around 980oC for an equivalence ratio of 0.5. The gas yield has been found to be in the range of 1.8 - 2.9 Nm3/Kg. The study has been carried out in a pilot model Gasifier.
