Abstract
As an alternative to a new and renewable energy source, bio-coal is generated through hydrothermal carbonization (HTC) which is a novel renewable energy production technology using waste. Therefore, bio-coal was generated through HTC reaction using wood waste, which is the most used biomass raw material and requires a recycling method and confirmed its possibility as a solid fuel. It can be seen that the higher the reaction temperature and the longer the reaction time, the higher is the fixed carbon content, which affects the heating value. At 300℃ and 4 h, the lowest heating value was 6841.23 Kcal/kg. In addition, the fuel ratio at 300℃ was 1.3 ~ 1.6, which indicates a higher fuel ratio range than that of low-grade coal, and it can be seen from the van krevelen diagram that the biomass region is closer to the lignite region.
