摘要：

In this study, kinetic studies and analysis of the produced syngas were conducted for low rank coal gasification under CO2 atmosphere. 6 coals were analyzed to measure amount of sulfur and ash by proximate and ultimate analyses. And then they were analyzed to select suitable sample by using Thermogravimetric analyzer (TGA). Selected coal sample Samhwa was mixed with catalysts. Mixed samples with catalysts were used to get activation energy under CO2 atmosphere by using Kissinger's method and shrinking core model (SCM). Also, analysis of produced syngas was performed by Gas Chromatography (GC). In this experiment, activation of the K2CO3 was the best performance, and result of the analysis of the syngas showed similar trend with result of the activation energy.
