Abstract

Recently, waste bagasse in large numbers only thrown away, burned, and have notbeen used optimally. Although bagasse has been used, the waste bagasse is still piling up and considered as waste that pollute the environment. To take advantage of this biomass waste, themethod chosen is a thermochemical decomposition in hot compressed water. A 100 mL autoclave used in the experiment was loaded with 5 g dry powdered bagasse, 0.25 g catalyst (sodiumcarbonate) and 65 mL water. After having blown with nitroqen, the autoclave washeated in the tube furnace until the temperature was 2800C, and then kept at this temperaturefor the desired time. The desired time variations are 65, 70, 75, 80, and 85 minutes. The liquidand the solid product removed from the autoclave were separated by filtration. The liquidproduct was distillated to obtain oil. The results showed that the maximum oil was obtained at2800C with an optimum heating time was 80 minutes. From the analysis by GC-MS methode,the oil obtained contains several compounds such as ketones, phenols and its derivatives,syringol and its derivatives, furan and its derivatives, and offrers.
