Abstract

The use of adsorbent media in the form of activated carbon is very necessary, especially in the refining industry of a product or for handling waste, so far activated charcoal is mostly made from biomass as raw materials such as coconut shell charcoal, wood, etc. However, by looking at the potential of coal in East Kalimantan, which has quite abundant coal, especially low-rank coal which is not utilized optimally. Low-rank coal or known as lignite has less economic value, this is due to its poor quality, low calorific value, and high sulfur and ash content, making it unsuitable for use as an energy source. However, this low-rank 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 to absorb impurities such as color and dissolved metals. The purpose of this study was to determine the characteristics of low-rank coal which was activated chemically and physically using the H3PO4-NaHCO3 activator. Coal was sieved with a size of -100+120 mesh and then carbonized at 6000C for 3 hours. After that, 20 grams of charcoal was activated using 2.5M H3PO4-NaHCO3 2.5M with variations in the activation process of combination activation and non-combination at temperatures of 7000C and 8000C. The best results were obtained in the Physico-chemical combination activation process at a temperature of 8000C with a water content of 4.14%; volatile matter content of 9.58%; ash content of 13.45%; fixed carbon content of 72.81% and iodine absorption of 1163.5129 mg/g.
