Abstract
In this study, the experiment of CO production was performed using carbon dioxide and coal. The synthesis characteristics of CO gas was investigated using the chemical activation method of KOH. The preparation process has been optimized through the analysis of experimental variables such as activating chemical agents to coal ratio, the flow rate of gas and reaction temperature during $CO_2$ conversion reaction. Without the catalyst of KOH, the 66.7% of $CO_2$ conversion was obtained at the conditions of $T=950^{\circ}C$ and $CO_2$ flow rate of 300 cc/min. On the other hand, the 98.1% of $CO_2$ conversion was obtained using catalyst of KOH at same conditions. It was found that the feed ratio(Coal : KOH = 4 : 1) had better $CO_2$ conversion and CO selectivity than other feed ratios.
