Energy requirement for cutting of different biomass materials depends on their properties and size which plays an important role in gasification process. In present study, the cutting energy required by the size reduction machine to cut selected different biomass materials viz., Pigeon pea stalk (Cajanus cajan), Cotton stalk (Gossypium hirsutum) and vilatyee babool (Prosopis juliflora) into different length of sizes viz., 25-50, 50-75 and 75-100 mm was assessed. And also their physico-chemical and thermal properties were determined using the standard procedure. The cutting capacity of different biomass material ranged from 21.35 to 32.13, 15.52 to 24.12 and 25.04 to 39.40 kg h-1 respectively for pigeon pea stalk, cotton stalk and vilaytee babool. Whereas, the energy requirement for cutting into selected sizes (25-50, 50-75 and 75-100 mm) ranged from 0.21 to 0.07, 0.16 to 0.07 and 0.14 to 0.04 MJ kg-1 respectively. The moisture content of different biomass material ranged from 3.28 to 9.45 per cent and maximum bulk density of 556 kg m-3 was observed for vilaytee babool, followed by pigeon pea stalk (501 kg m-3) and minimum of 465 kg m-3 for cotton stalk. Whereas, maximum volatile matter content of 80.81 per cent was observed for vilaytee babool and a minimum of 80.20 per cent for cotton stalk. The calorific value of 16.44, 16.05 and 17.49 MJ kg-1 was observed for pigeon pea, cotton stalk and vilaytee babool, respectively.
