Abstract

East Kalimantan is one of the provinces in Indonesia that produces the largest coal. Brown coal or known as lignite has less economic value, this is because of its poor quality, low heating value and high sulfur and ash content, so it is not suitable for use as an energy source. However, lignite coal has the potential to be used as activated carbon which is an absorbent medium because it has a fixed carbon content of 25-30%. As activated carbon, low rank coal will be very useful for absorbing impurities such as color and dissolved metals. The purpose of this study was to determine the adsorption of browncoal from East Kalimantan from the Kutai Kertanegara area which was activated using the H3PO4-NaHCO3 activator on the quality of the activated carbon produced. Coal is sifted with a size of -100+120 mesh and then carbonized at 600oC for 3 hours. After that, 20 grams of charcoal was activated using 2.5M H3PO4-NaHCO3 2.5M with time variations of 2 hours, 4 hours, 6 hours, 8 hours and 12 hours, then washed to a neutral pH and then physically activated at 700oC for 2 hours. The best results were obtained with chemical activation for 6 hours with a water content of 3.5%; volatile matter content 9.81%; ash content 14.91%; fixed carbon content 71.78% and iodine absorption 505.072 mg/g.
