Pembuatan Dan Karakterisasi Karbon Aktif Dari Biomassa Tandan Kosong Kelapa Sawit Melalui Modifikasi Alat Pra-Karbonisasi
ABSTRACT
Activated carbon derived from empty palm oil fruit bunches in powder form has been successfully prepared. The initial preparation starts from taking the raw ingredients followed by the pre-carbonization combustion process using a furnace by varising burning time of 20 minutes, 30 minutes, 40 minutes and 50 minutes. Neutralization and grinding processes are carried out on the charcoal produced from pre-carbonized combustion. The sample powder produced was then carbonized using N2 gas and physically activated using H2O gas at a temperature of 600⁰C to 850⁰C with variations in holding times of 2 hours, 2.5 hours and 3 hours. Characterization of activated carbon were examined using XRD characterization and N2 gas absorption. The resulting activated carbon is amorphous with a specific surface area of 396.465 m2/g, 377.826 m2/g and 230.383 m2/g for the samples TKKS-2, TKKS-2.5 and TKKS-3, respectively. The TKKS-2, TKKS-2.5 and TKKS-3 samples also had a microporous surface area of 344.854 m2/g, 320.653 m2/g and 182.663 m2/g, respectively. The results of the characterization carried out show that the surface area of the sample is directly proportional to the volume of micropores, where the greater the surface area of the activated carbon sample, the greater the volume of micropores produced, this is in accordance with the results of N2 gas absorption characterization where the TKKS-2 sample has an area higher surface area of 396.465 m2/g also has a higher micropore volume value of 0.176708 cm3/g.
