| 摘 要： | 应用穆斯堡尔谱考察了焙烧温度对成型氧化铁脱硫剂相态组成的影响．实验结果表明，提高焙烧温度有利于α－Ｆｅ２Ｏ３的形成，但焙烧温度过高则会使α－Ｆｅ２Ｏ３转变成Ｆｅ３Ｏ４并引起部分成分烧结而导致脱硫剂活性的下降原脱硫剂中的Ｆｅ２Ｏ３在焙烧过程中转化成α－Ｆｅ２Ｏ３和Ｆｅ３Ｏ４．再生处理后脱硫剂的化学组成基本上可恢复至起始状态．

| Abstract: | Mossbauer effect was used tO study the chemical constipation of iron oxide desulphurizer prepared under different conditions. Experiments show that the content of a- Fe2O3 is increased with the increase of calcination temperature.The a-Fe2O3 was convented intO Fe3O4 and the desulfurization activity was decreased as the calcination temperature was increased further. The composition of the desulphurizer can be restored to its original state by regeneration. |
