Abstract

This study evaluated the effects of carbonization conditions on the char properties of fallen leaves originated urban area. As the disposal of urban fallen leaves has been one of the serious environmental issues, their carbonization could be a reliable method for increasing their usability. Continuous carbonization instrument was devised for this study. The fallen leaves were transferred using a screw conveyor, which made it possible to control the time for carbonization. The degree of carbonization depending on carbonization conditions such as time and temperature were evaluated by elemental analysis, particularly the compositional ratio of the carbon element. Moreover, carbonization increased the pH of the char of fallen leaves. The yield of the char of fallen leaves was decreased; however, the micro-pore structure was increased by increasing the carbonization time. The higher porosity of the fallen leaves char resulted in a higher iodine adsorption ability.
