Method for direct reduction of iron using high sulfur gas |
摘要 |
A method for the direct reduction of iron oxide utilizing sulfur-containing gas such as coke oven gas for the process gas. Sulfur-containing gas is heated and injected into a shaft furnace above the reduction zone into a prereduction and sulfur transfer zone for transferring sufficient sulfur from the process gas to the burden, that the catalyst for reforming the spent top gas will not be poisoned.
