Abstract：

The　steam　gasification　kinetics　of　Chuanghong　anthracite　by　using　sodium　dodecyl-benzenesulfonate　and　sodium　citrate　as　catalysts　was　investigated　in　an　isothermal　thermo-gravimetric　analyzer　under　ambient　pressure.　The　relationships　between　coal　conversion　and　reaction　time　at　different　catalyst　concentrations　(0-15%)　was　studied　within　the　temperature　range　of　850-950°C.　The　catalytic　steam　gasification　reaction　was　well　fitted　by　the　shrinking-core　model　and　the　kinetic　parameters　were　obtained.　The　research　results　showed　that　both　catalysts　can　greatly　improve　gasification　rate　and　remarkably　reduce　the　activation　energy　of　gasification　reaction.　Sodium　dodecylbenzenesulfonate　has　the　same　catalytic　effect　as　sodium　carbonate　and　better　catalytic　effect　than　sodium　citrate　on　gasification　rate,　so　it　is　a　good　catalyst　for　catalytic　gisification　of　anthracite.
