Abstract

Current investigation was followed by characterization of pigeonpea briquettes, soybean briquettes and Prosopis juliflora. Proximate, ultimate and thermogravimetric analysis (TGA) of, pigeonpea and soybean briquettes was done by standard procedure and compared with Prosopis juliflora (woody biomass). The calorific value of Prosopis juliflora, pigeonpea and soybean briquettes was 18.41, 18.52 and 18.35 MJ/ kg, respectively. The volatile matter content of Prosopis juliflora, pigeonpea and soybean briquettes was 83.64, 76.02 and 76.89 % (d.b.), respectively. The ash content of Prosopis juliflora, pigeonpea and soybean briquettes was 1.14, 5.01 and 6.11 % (d.b.), respectively. The carbon content of Prosopis juliflora, pigeonpea and soybean briquettes was 49.86, 43.35 and 39.9 %, respectively. Thermogravimetric analysis of Prosopis juliflora, pigeonpea and soybean briquettes was done at 10, 20, 30 and 40 oC heating rate. It was found that at 30 oC heating rate the thermal decomposition of pigeonpea and soybean briquettes was same as Prosopis juliflora

Abstract

Study of effect of temperature on iodine value of bio-char and total carbon contain in bio-char was studied in continuous feed reactor with 1 kg/hr feeding rate. The temperature on iodine value of bio-char and total carbon contain as taken at different temperature of 450, 500, 550 and 600°C, respectively in both condition. The yield of the activated carbon in bio-char was decreased 38.1 to 37.54 per cent with the increase in pyrolysis temperature 450 to 550°C. However, the iodine adsorption capacity of the prepared activated carbon increased from 167.7 to 288.78 mg/g with an increase temperature 450 to 600°C in condition 1. In condition 2 the yield of activated carbon was decreased 37.02 to 26.66 per cent with the increase in pyrolysis temperature 500 to 600°C. However, the iodine adsorption capacity of the prepared char decreased 214.67 to 154.158 mg/g with a temperature 450 to 600°C. Based on comprehensive consideration of yield and iodine adsorption capacity of the char prepared, 600 and 500°C was chosen for optimum pyrolysis temperature in condition 1 and condition 2, respectively.
