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．
The influence of calcination temperature on the phase composition of the shaped iron oxide desulfurizer was investigated by using Mössbauer spectroscopy. The experimental results show that increasing the calcination temperature is beneficial to the formation of α-Fe2O3, but the calcination temperature is too high will make α-Fe2O3 into Fe3O4 and cause some components to sinter and lead to the desulfurization activity of the desulfurization agent desulfurization agent in the roasting process Into α-Fe2O3 and Fe3O4. After the regeneration treatment, the chemical composition of the desulfurization agent can be basically restored to the initial state.
