Coal is spotlighted as a top priority energy resource which will replace oil. Coal gasification can reduce amount of carbon dioxide(CO<SUB>2</SUB>), sulfur oxides(SOx) and nitrogen oxides(NOx). Also, it produces mono dioxide(CO) and Hydrogen(H<SUB>2</SUB>). However, typical-type coal gasification technology is required huge amount of energy at high temperature over 1000℃. Therefore, catalyst(K<SUB>2</SUB>CO<SUB>3</SUB>) is added to decrease operation temperature and reduce amount of energy. In this experiment, Roto ultra clean coal(UCC) and Roto original coal(OC) are used. And coal char is produced for this experiment. The experiment is progressed with 1g of coal char with potassium carbonate(K<SUB>2</SUB>CO<SUB>3</SUB>) under flowed 500ml/m of steam(H<SUB>2</SUB>O) as a reactant and 2000ml/min of nitrogen as carrier gas. With this condition, it is progressed for 1hr under different designated temperature(600, 700, 800℃) and different catalyst conditions. From those experiments, the carbon conversion ratio is calculated and compared the gasification reactivity
