Stydy on Catalytic Combustion Effect of Coal-burning Additive with Thermogravimetric Method

The combustibility of Fengcheng tipot coal and catalytic combustion effect of the rare earth(RE) coal burning additive on this coal doped were studied by TG and DTG with linearly increasing temperature at air atmosphere.For Fengcheng tipot coal and this coal doped with 5% the RE coal burning additive,α(-ΔW/ΔW end )are 51.3% and 57.59%.the activation energies were 1 075 kJ/mol and 485.0 kJ/mol,the reaction orders were 4.5 and 7.7,respectively.Experimental results show that ER coal buning additive have high catalytic efficiency on this tipot coal combustion.
