摘要: 采用氣相質譜在線監測反應氣體成分變化的方法,研究了1273~1473 K范圍內,不同比例CO₂-CO混合氣體對鐵片恒溫氧化的反應動力學.結果表明,氧化反應速率與二氧化碳分壓呈線性關系,反應速率常數隨CO₂/CO體積比值增大而減小,鐵片氧化反應的表觀活化能為（137.7±15.8）k J·mol^-1.該方法得到的結果與文獻相比較,結果是可靠的,表明該方法可以用來在線研究氣-固反應的動力學.

Abstract: 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.
