THE MAKING OF ACTIVATED CARBON FROM WOOD CHARCOAL WITH ACTIVATION PHOSPHORIC ACID USING FURNACE

Abstract

Furnace Unit is a source of heat transfer equipment which the heat generated from combustion of fuel by the burner in the fire box, whether it be Fuel Gas, Fuel Oil, or other type of fuel with air, where is the heat generated transferred into the crude oil which flowing in the tube. Furnaces used in this experiment are muffle furnace type. Activated carbon is an amorph carbon compounds, which produced from materials containing carbon or charcoal that treated in a special way to get a wider surface. Activated carbon manufacturing process begins with the process of carbonization, and then activation .Karbon has a function as an adsorbent. In this experiment, the raw material used is wood charcoal. Because the wood charcoal has the form of carbon, so it doesn’t need carbonization but directly activated by phosphoric acid and then heated in a furnace at temperature of 500 ° C, 600 ° C, 700 ° C and 800 ° C with 5%, 10%, 15%, 20 % solution concentration, then analyzed the adsorption capacity of iodine solution. From the results of this experiment gotten the best activated carbon is the activated carbon which heating at temperature of 700 ° C and a concentration of 10% activation with adsorption power of 888 mg / g Keywords: wood charcoal, activated carbon, absorption.
