助燃催化剂对煤粉在高炉喷吹快速热解中的影响

Influence of Combustion Catalysts on Rapid Pyrolysis of Mixer Coal in Pulverized Coal Injection on Blast Furnace

选取KMnO4、Fe2O3、MnO2和CaO作为助燃催化剂,采用H2/Ar等离子体热解试验装置和快速升温热解红外连用试验装置来模拟煤粉在高炉喷吹条件下的快速热解过程,对混合煤粉的快速热解过程进行了研究,得到了助燃催化剂与煤的裂解程度(裂解气体收率)、裂解气体成分的关系,对助燃催化剂的催化裂解机理进行了讨论。

Based on the experiments stimulating the condition of blast furnace operation by plasma and Py-FI＇IR, the influence of combustion-supporting agent （KMnO4,Fe2O3,MnO2 and CaO） as catalyst on rapid pyrolysis of the mixer coal in pulverized coal injection on blast funace is studied. The effect of catalyzator on yield of coal conversion is analysed. The relationship of catalyst and concentration of production gas is analysed too. The mechanism of this catalytic action is studied.
