Utilization Biomass and Coal Mixture to Produce Alternative Solid Fuel for Reducing Emission of Green House Gas
This paper presents the characteristics of bio-briquette resulted from a series process using a mixture of raw materials. As raw materials of biobriquette production, this research used biomass corn cobs and banana peels, and a fine coal waste. Before using as component in the biobriquette, corn cobs, banana peels, and fine coal waste were carbonized. The carbonation process was carried out in temperature of 300-500oC for 15 minutes. Carbonized corn cobs, banana peels, and a fine coal waste were characterized for calorific value and ash content. In this work, the influence of composition carbonized biomass and carbonized coal has been investigated. Before and after carbonization of biomass and coal, the calorific value and ash content of corn cobs were 4,239-6,386 kcal/kg and 3.47-8.12 % adb respectively, for banana peels were 4,135-6,042 kcal/kg and 16.99-32.31 % adb respectively, and for coal were 5,857-6,330 kcal/kg and 5.81-6.64 % adb respectively. The highest calorific value of biobriquette of 6,297 kcal/kg, highest fixed carbon content of 62.62 %, lowest volatile matter content of 26.18 % adb, lowest inherent moisture content of 5.14 % adb and lowest ash content of 6.06 were measured for composition of carbonized coal, carbonized corn cobs and carbonized banana peels ratio was of 1:4:0.
