PROCESS FOR THE CHLORINATION OF OXIDIC MATERIALS |
| 摘要 |
The fluidised bed chlorination of oxidic ores having a surface area of at least 3.5 m<2>/g such as ilmenite or bauxite may be accomplished at temperatures below 772 DEG C in the presence of a coke derived from a non-caking or weakly caking coal which has been heated in the substantial absence of oxygen until its surface area is at least 3 m<2>/g. The invention provides an alternative to active carbon. |
