Abstract
Coal is an organic rock formed from fossilized plants that are dark in color and associated with mineral content such as ash and sulfur. The overall process is influenced by environmental conditions, temperature, and pressure. There are 3 grades of coal including lignite (brown coal), bituminous, and anthracite. Coal is brown to black in color, consisting of 3 main contents: carbon, hydrogen, and oxygen atoms. Anthracite has the highest carbon content among other types of coal and has a carbon content of more than 87% with a dry ash-free content. Anthracite is the best type of coal because it has the largest carbon content among the three, so this research used Anthracite coal. The carbon content contained in coal can be utilized to become activated carbon which functions as an adsorbent. The purpose of this research is to study the effect of coal to KOH ratio and physical activation temperature on the surface area and adsorbing power of activated carbon from coal. The research method used is dehydration first at 110°C, then carbonization at 800°C. The next step is chemical activation and physical activation. The results after activation will be analyzed for moisture content, ash content, fly content, bound carbon content, and iodine number as well as surface area analysis and Pb adsorption test based on SNI 06-3730-1995. The results obtained from this study are the best KOH usage ratio and optimum temperature to activate coal, namely in the ratio of coal to KOH 1: 5 with a temperature of 700 ° C with a Bound Carbon Content of 77.1% which is in accordance with the levels of SNI 06-3730-1995. And a surface area of 317,328 m2 /g.
