Kenevi̇r Atiklarinin Karboni̇zasyonu Ve Akti̇f Karbon Eldesi̇

Abstract

In this research, waste parts (root, stem and other) of hemp grown in Malatya Turgut Özal University Faculty of Agriculture were evaluated. Activated carbon was obtained from hemp waste by using carbonization and chemical activation method and characterization experiments were carried out. Elemental (C, H, N, S) analysis, XRD, FTIR and SEM analyzes were performed to determine the characterization of the activated carbon samples. In addition, the surface area and porosity of activated carbons were determined by BET nitrogen adsorption surface area measurement. The total surface area (Stotal) of the carbonized hemp waste is 171.75 m 2 /g, the micropore area (Smicro) is 145.46 m 2 /g and the mesopore area (Smezo) is 26.29 m 2 /g. These values were calculated as 1881.80 m 2 /g, 1152.40 m 2 /g and 728.40 m 2 /g, respectively, inactivated carbon impregnated with KOH at a 1:4 ratio. The pore volume of 0.077 cm 3 /g in the carbonized product was determined as 0.8852 cm 3 /g in activated carbon. The average pore diameters (dp) of the carbonized product and activated carbon were determined as 1.78 nm and 1.88 nm, respectively. According to these results, it has been determined that it is possible to obtain activated carbon economically by carbonization and chemical activation of hemp waste.
