Fındık küspesi ve kahve atığından aktif karbon üretimi ve karakterizasyonu.

Activated carbon is a porous material with a wide range of applications. Activated carbons derived from natural and agricultural sources are more cost effective and sustainable. Therefore, studies on activated carbons synthesized from biomass have increased. The aim of this study was to utilize waste resources such as hazelnut meal and waste coffee grounds as activated carbon. Activated carbons with impregnation ratios of 2:1, 3:1 and carbonization temperatures of 400°C, 500°C, 600°C were prepared from hazelnut bagasse and coffee waste by chemical activation with ZnCl2. BET, SEM-EDS and FTIR analyses were performed to determine the surface properties of the activated carbons. The highest surface area of 846 m²/g was obtained in activated carbons obtained from hazelnut bagasse at 3:1 impregnation ratio and 500°C temperature. The largest total pore volume was obtained as 0.645 cm³/g. The highest surface area of 747.5 m²/g was obtained for the coffee waste activated carbons at 3:1 impregnation ratio and 500 °C temperature.
