Abstract

This research is looking for combustion characteristics of charcoal products that produced from the hydrothermal process of biomass waste and LDPE type plastic waste in sub-critical water with various operating conditions. The hydrothermal process is carried out using a Batch Type Reactor with the main steam heater produced by a mini boiler and an external heater obtained by the gas burner as a secondary heater. The operating conditions of the hydrothermal process are designed at low pressure, which is 4-6 Bar with a temperature range of 130 oC - 170 oC. The parameters examined in this study were the final weight of the charcoal product, the percentage of mass reduction and the combustion characteristics of the solid product produced by the hydrothermal process which included the maximum temperature of the flame, the stability of the fire and the rate of combustion. The results showed that the hydrothermal process of biomass waste and plastic waste can be carried out at lower pressures, only to get better product quality higher temperatures are needed. The temperature of the hydrothermal process has a major effect on the quality and magnitude of the weight percentage of the final product (charcoal). The more the temperature of the hydrothermal process, the greater the percentage of the weight of the final solid product (charcoal) will be smaller accompanied by the increasing quality of the product. The hydrothermal process to biomass waste and plastic waste can increase carbon content in charcoal products so that the quality of both waste as an alternative fuel also increases. Based on the percentage of weight and quality of the solid product (char), the optimum conditions of the hydrothermal process studied were obtained at a temperature of 155 oC - 160 oC, a pressure of 5 Bar - 6 Bar with a holding time of 2 hours. The temperature of the hydrothermal process and the type of waste also affect the combustion characteristics of the charcoal product produced by the hydrothermal process.
