Gasification of iron coke and cogasification behavior of iron coke and coke under simulated hydrogen-rich blast furnace condition
文献摘要：
To explore the iron coke application in hydrogen-rich blast furnace, which is an effective method to achieve the purpose of low car-bon emissions, the initial gasification temperature of iron coke in CO2 and H2O atmosphere and its cogasification reaction mechanism with coke were systematically studied. Iron coke was prepared under laboratory conditions, with a 0–7wt％ iron ore powder addition. The proper-ties of iron cokes were tested by coke reactivity index (CRI) and coke strength after reaction (CSR), and their phases and morphology were evolution discussed by scanning electron microscopy and X-ray diffraction analysis. The results indicated that the initial gasification temperat-ure of iron coke decreased with the increase in the iron ore powder content under the CO2 and H2O(g) atmosphere. In the 40vol％ H2O + 60vol％CO2 atmosphere, CRI of iron coke with the addition of 3wt％ iron ore powder reached 58.7％, and its CSR reached 56.5％. Because of the cata-lytic action of iron, the reaction capacity of iron coke was greater than that of coke. As iron coke was preferentially gasified, the CRI and CSR of coke were reduced and increased, respectively, when iron coke and coke were cogasified. The results showed that the skeleton function of the coke can be protected by iron coke.
