Abstract
In this study, the experiments on optimal CO gas synthesis were conducted using low grade coal-$CO_2$ catalyst gasification reaction. The characteristics of generated CO gas were investigated using the chemical activation method of KOH, $K_2CO_3$, $Na_2CO_3$ catalysts with Kideco and Shewha coal. The preparation process has been optimized through the analysis of experimental variables such as ratio between activating chemical agents and coal, the flow rate of gas and reaction temperature during $CO_2$ conversion reaction. The produced CO gas was analysed by Gas Chromatography (GC). The 98.6% $CO_2$ conversion for Kideco coal mixed with 20 wt% $Na_2CO_3$ and 98.9% $CO_2$ conversion for Shenhua coal mixed with 20 wt% KOH were obtained at the conditions of $T=950^{\circ}C$ and $CO_2$ flow rate of 100 cc/min. Also, the low grade coal-$CO_2$ catalytic gasification reaction showed the CO selectivities(97.8 and 98.8 %) at the same feed ratio and reaction conditions.
