| 中文摘要 | TG-DTG and DTA determination indicated that ignition temperature of anthracite was lowered from 458℃ to 405℃ by addition of 10% catalyst Fe2O3.Based on the nature of anthracite ignition temperature,pyrolysis conversion and pyrolysis gas composition during the catalytic combustion were examined.The results showed that with Fe2O3 addition anthracite pyrolysis conversion was 3.0% at 405℃ and components with higher heating value increased in the pyrolysis gas.However,without Fe2O3 addition pyrolysis conversion was 1.8% at ignition temperature.It could be concluded that the heat from the homogeneous combustion of catalytic combustion was higher than that of non-catalytic combustion.TG-DTG indicated combustion conversion of 10 % at ignition.SEM images of chars indicated rough surface of char with plenty of small pores.BET of char from catalytic combustion was 170 m2·g-1 while BET of char from non-catalytic combustion was only 128 m2·g-1,which could be the main reason for lowering ignition temperature.The results from oxygen adsorption experiment showed increased oxygen content of coal with catalyst addition,which caused faster oxygen adsorption at a lower temperature and shortened the time to get required oxygen concentration and heat accumulation for ignition,thus the ignition temperature was lowered. |
