Carbon-composite briquetting of iron ore fines & fast

In the carbon-composite briquettes, the distance between iron ore & carbon is shortened, so that the reduction of iron ore & the gasification of carbon occur rapidly at the same place. CO 2 produced from the reduction is used for the gasification to generate CO simultaneously....

Reduction of Iron Ore/Empty Fruit Bunch Char Briquette

The Fe content in the ore was greatly increased up to 62.7 wt% suggesting that EFB char can be potentially used as a reductant for upgrading low grade iron ore through reduction process. Other than that, the reduction of briquette was controlled by gasification of carbon where the activation energy is 43.21 kJ/mol.
