Temperature Effect on Densification of Banana Peels Briquette

Abstract

As a lignocellulose source, banana peel has possibility to convert to be a solid biofuel. This current research applied Tanduk banana peels waste for main material of briquette. The aim of this research is to observe the effect of temperature during carbonization of banana peels and its impact on densification of banana peel to produce a high quality of briquette. Carbonization temperature of banana peels was carried at three different temperatures of 270 (C270), 370 (C370) and 470 (C470) oC. The densification of carbonized banana peel was 40.0 tons. Furthermore, densification also performed on the non carbonization of banana peel (NC) on order to compare the results without presence of any binder materials. Initial results involved proximate analysis to fulfill the briquette standard requirement and compressive analysis to investigate the strength of briquette. The proximate analysis shown that moisture content of carbonized briquettes were about 5.00 to 6.06 %, ash content were about 20.59 to 30.03 %, volatile matter were about 61.91 to 70.15 % and fixed carbon were about 2.00 to 3.80 % respectively. These findings quite different with non-carbonized briquette. In addition, the compressive analysis obtained that the non-carbonized (NC) briquette produce the highest compressive load limit. Compressive analysis is important to know the ability of briquette to resist the load for logistics purposes. The preliminary results support the idea that banana peels waste are potential to be process as a briquette of solid biofuel.
