Abstract
Hydrothermal carbonization (HTC) is a carbonization method of thermochemical process at a relatively low temperature (180-250℃). It is reacted by water containing raw material. In this study, it was selected for effective disposal method of food waste because food waste in Korea has large amount water. 5 kg, 10 kg, 15 kg of food waste were reacted for 6 hours at 200℃ for selecting the optimum amount of raw material. Since the derived optimum amount, food waste was reacted for 2 hours, 4 hours and 6 hours at 200℃ and 1.5 MPa. After carbonization, it was analyzed to evaluated the properties by ultimate analysis, iodine adsorption, BET surface area and SEM. After analyzing the characteristics, it can be utilized as a basic data for applied.
