Using　sodium　carbonate　as　the　catalyst,　the　carbon　dioxide　gasification　kinetics　of　the　four　high　rank　anthracites　(Vad　=　2.　69%　[similar　to]　4.　35%)　was　investigated　by　isothermal　thermo-gravimetric　analysis　under　high　pressure.　The　range　of　pressure　from　0.101　MPa　to　3.0　MPa　was　tested.　The　results　show　that　when　the　pressure　is　higher　than　2.　0　MPa,　the　increase　of　pressure　has　no　effect　on　the　reaction　rate.　The　coal　conversion　as　a　function　of　reaction　time　was　measured　at　the　temperature　from　750°C　to　950°C　and　at　2.　0　MPa,　which　could　be　preferably　correlated　by　the　shrinking-core　model　(SCM).　According　to　the　reaction　rate　constant　determined　by　SCM,　the　reactivity　order　of　the　four　anthracites　is:　Yongan　Fengshai　coal　＞　Yongan　Jiashai　coal　＞　Yongding　coal　＞　Shangjing　coal.　The　activation　energies,　ranging　from　157.　21　kJ/mol　to　185.　89　kJ/mol,　are　obtained.　The　reaction　rate　constant,　activation　energy　and　pre-exponential　factor　under　high　pressure　are　larger　than　those　of　the　gasification　in　CO2　at　atmospheric　pressure.　At　850°C　the　power　of　CO2　partial　pressure　for　Yongan　Jiashai　coal　is　0.　347　44,　which　agrees　well　with　the　literature.
