摘要：

The gas-solid coupling reaction between sinter and coke was analyzed by the thermogravimetric method with a nonisothermal heating rate not fixed. The reaction was suitable for the relevant kinetic parameters of chemically controlled gas-solid reaction. The new method is applied to the gas-solid coupling reaction of ore and coke heated to 1200 degrees C. In the calculation of the new method, the kinetic parameters of the coupling reaction between sinter and coke with large dosage and size are obtained by using the change of gas concentration in several groups of heating experiments and the introduction of model-free method (isoconversional method). The effectiveness of the new method is verified by comparing the results of nonisothermal kinetic experiments with the corresponding isothermal experiments.
