Oxidation kinetics of iron and CO2-CO by using gas mass spectrometry method
The oxidation kinetics of iron sheet in CO2 -CO mixture was studied by on-line measuring the composition change of the reaction gas using a gas mass spectrometer under different CO2 partial pressures in the temperature range of 1273 to 1473 K. It is found that the oxidation rate increases linearly w...

| description | The oxidation kinetics of iron sheet in CO2 -CO mixture was studied by on-line measuring the composition change of the reaction gas using a gas mass spectrometer under different CO2 partial pressures in the temperature range of 1273 to 1473 K. It is found that the oxidation rate increases linearly with CO2 paltial pressure, the rate constant decreases with the increase of COJCO volume ratio, and the apparent activation energy of the oxidation of iron sheet is (137.7±15.8)k J·mol-1. Compared with the results reported, this on-line mass spectrometry analysis can get reliable resuhs, so it can be used to study the gas-solid reaction kinetics. |
