| Abstract: | The pyrolysis and gasification behavior of five-coal samples in the same coalification degree but different reductive degree were investigated by continuous coal pyrolysis-gasification with TG-DTG-DSC.The kinetic parameters of coal pyrolysis were obtained by Coats-Redfern integral method.The result shows that the third order chemical reaction model is adapt to the whole temperature range and the pyrolysis mechanism of five coals is similar.The apparent activation energy range of pyrolysis is 43-54 kJ/mol fo... |
