Production of briquettes from Indonesia agricultural biomass waste by using pyrolysis process and comparing the characteristics

Abstract

Indonesia biomass waste is a potential feedstock as a source of renewable energy since it can be converted into carcoal briquettes. However, the production of the briquettes using pyrolysis process using the agricultural waste was lacking. In this research, briquette was made from palm shells, corncob and soybean stem wood due to its high availability and have high cellulose content. The purpose of this research was to produce briquettes from three kind of raw materials by employing pyrolysis process and compared the characteristics. The briquette was made from different type of raw materials (palm shells, corncob and soybean stem) and the concentration of binder : 3-7 %. Pyrolysis was done at 500 °C, and 100 kg / cm2 of pressing pressure. Results showed that, the best charcoal briquette was achieved from palm shells by using 5% binder, which resulted 4,1% moisture content, 3.4% ash content, 15% volatile matter content, 77.5% carbon content, 7075 cal/g calorific value and 1.4 kg/cm2 compresive strength. It is found that the concentration of binder and raw material influenced the quality of the briquettes. In overall, the production of the briquettes by employing pyrolysis method could meet the standard.

Analysis of Fixed Carbon and Volatile Matter Briquettes of Pine Sawdust and Coconut Shell Waste

“…The fixed carbon content affects the quality of the briquettes, the higher the fixed carbon content, the better the quality of the briquettes produced [28] . The lower the volatile matter, the bigger the fixed carbon content, [2] , appropriated with equation (1).…”

“…Biomass become a great energy source because there are so many raw materials can be used for energy includes, agricultural residues, manure, wood slivers, food residue, wastewater and garbage [1] . After coal and petroleum, biomass become the third largest energy resource [2] . Biomass in Indonesia has a potential of 103 million tonnes per year which is just utilized as alternative energy by 42% [3] .…”

Energy Yield of the Carbonized Plant Leaf, Petiole and Branch Biomass Briquettes for Sustainable Production of Future Fuels

“…There is another requirement of the briquette that should be not easy to break, not brittle and have smooth surface. It should also not leave black to the hand [15]. It can be seen that there are different results of the briquette under pressure 20 N/cm 2 and 50 N/cm 2 for the same material of the briquette such as that under the pressure of 20 N/cm 2 showed of more sturdy of the briquette, not easy to brake, compact but might have different appearance of surface, either rough (i.e., Rambutan and Guava) or soft (Langsat).…”
