An experiment was conducted to study the performance of cattle dung at different total solids (TS) viz., 10, 12, 15 and 18 per cent in three in prototype digesters of 1:0.5, 1:1 and 1:1.7 (H/D ratio) size for a retention period of 56 days under laboratory conditions. The results indicated that, at 10% TS, the cumulative gas production was maximum (345.8 litres) in 1:1.7 H/D size digester followed by 1:1 size digester (305.2 litres) and 1:0.5 size digester (255.8 litres) at the end of retention period of 56 days. While the maximum cumulative gas production of 393.9 litres was recorded in 1:1.7 H/D size digester followed by 1:1 size digester (358.1 litres) and 1:0.5 size digester (297.0 litres) at the end of retention period of 56 days at 12% TS . Whereas at 15 % TS, the maximum cumulative gas production of 474.5 litres was recorded in 1:1.7 H/D size digester followed by 1:1 size digester (419.3 litres) and 1:0.5 size digester (348.4 litres) at the end of retention period of 56 days. It was observed that the cumulative gas production was maximum in 1:1.7 H/D size digesters followed by 1:1 H/D size digester and 1:0.5 H/D size digester at all the total solids fed. The average percentage of methane content was maximum (57.09 %) in the gas produced from cattle dung at 15 per cent TS in 1:1.7 size (H/D ratio) digester, whereas a minimum of 52.48 percentage of methane content was recorded in the gas produced from cattle dung at 10 per cent TS in 1:0.5 size (H/D ratio) digester.Keywords

Agricultural and forest biomass material were reported to be the potential feedstock for gasification by various researchers. The physical, chemical and thermal properties of biomass material play very important role in order to characterize the feedstock for energy conversion process. The physical properties (moisture content and bulk density), chemical properties (volatile matter content, ash content and total carbon content) and thermal properties (calorific value) of selected agricultural and forest biomass viz., pigeonpea stalk (Cajanus cajan), cotton stalk (Gossypium hirsutum) and vilaytee babool (Prosopis juliflora) for different length of sizes ranging from 25-50, 50-75 and 75-100 mm were determined using standard procedures. The moisture content of pigeonpea stalk, cotton stalk and vilaytee babool were found to be 3.28, 6.98 and 9.45 per cent, respectively. While the bulk density of these feed stock were reported to be 501, 465 and 556 kg m-3, respectively. The volatile matter content, ash content and total carbon content of pigeonpea stalk were 80.67, 1.39 and 17.94 per cent, respectively. While for cotton stalk these were 80.20, 1.43 and 18.37 per cent. Whereas, vilaytee babool these were 80.81, 1.83 and 17.36 per cent, respectively. The calorific value of 16.44, 16.05 and 17.49 MJ kg-1was observed for pigeonpea, cotton stalk and vilaytee babool, respectively. The results obtained from the study indicated that the selected agricultural and forest biomass material were found to be potential for thermal gasification.Keywords
