| 摘 要： | 研究了影响高铁赤泥煤基直接还原的主要因素，并对其催化还原机理进行了初步探讨。比较理想的还原条件是配加１倍理论碳量的低灰分含量、灰分组成值高且反应活性和（Ｆｃ＋Ｖｍ）／（Ａ＋Ｗ）值高并能产生适中孔隙率的还原煤，并添加强碱性添加剂加以催化。

| Abstract: | The main factors affecting the coal-based direct reduction of high-iron-content red mud as well as the catalysis mechanism were studied in this paper. On the basis of the results obtained,we found that the ideal reduction condition is the use of the reductive coal having the carbon contents as much as theoretically needed along with a strong-base additive which acts as a catalyst. The coal used must have the following quality : low ash content,high reactivity,large ratio of (Fc Vm)/ (A W) and ash compoition (SiO2 TFe)/(Al2O3 other),able to form the moderate porosity. |
