Carbon dioxide emissions contributed by fossil fuel, have become a severe concern in relation to global warming and health issues. High content of CO 2 will caused low content of heat value. This study is to reduce the concentration of CO 2 gas by adsorption using K 2 CO 3 rice husk. The method used is adsorption using a laboratory scale fixed bed column equipment at atmospheric condition and room temperature. The adsorption column was filled with K 2 CO 3 and rice husk which composition (50: 8; 75: 8; 100: 8; 125: 8) grams, CO 2 gas flowed from the bottom of the column which flow rate 9 liter per minutes (LPM). Then the sample was taken at the top of the column every 5 minutes. It showed that the highest adsorption capacity is 7.54 percent CO 2 removal/gr adsorbent which amount of K 2 CO 3 adsorbent 50 gr at 9 LPM CO 2 inlet flow rate. It showed that most adsorbents have the most active sites to adsorb CO 2 . It also showed that K 2 CO 3 50 gr have the longest breakthrough time than others amount of K 2 CO 3 .
