Study on Coal-Based Hydrogen-Carbon Coupling for Reducing Iron in Nickel Slag
A study explored coal-based hydrogen-carbon coupling technology to reduce iron in iron-rich nickel slag, revealing that the reaction order decreased and the reaction rate constant increased with higher temperatures. Specifically, as the reduction temperature rose from 1200°C to 1300°C, the reaction order fell from 1.63 to 1.33, while the reaction rate constant increased from 0.031 to 0.165. The apparent activation energy for the reduction process was measured at 40.35 kJ/mol.

This study investigated coal-based hydrogen-carbon coupling reduction technology for reducing iron-containing phases in iron-rich nickel slag. The reaction order for reducing FeO to Fe was calculated using the differential method and validated through experiments.
Results showed that the reaction order decreased with temperature increases, while the reaction rate constant rose. Specifically, as the reduction temperature increased from 1200°C to 1300°C, the reaction order decreased from 1.63 to 1.33, and the reaction rate constant increased from 0.031 to 0.165. The apparent activation energy for the reduction process was determined to be 40.35 kJ/mol.
