Modeling and Simulation for HyREX Hydrogen-Based Ironmaking
Research Objectives

The study aimed to provide a reliable engineering tool to predict chemical reduction efficiency and heat-flow behavior, moving beyond simple empirical data to a physics-based simulation approach.

Research period

September 2022 ~ September 2026

Core Technical Achievements

Advanced Resistance Network : Implemented a refined resistance model (Gas Film, Diffusion, Chemical Reaction) covering 10 detailed reaction pathways.

RTD-Kinetics Integration : Developed a methodology to quantify the efficiency gap between batch and continuous reactors resulting from non-ideal back-mixing.

Exceptional Accuracy : Achieved an error margin of less than 2% compared to experimental data.

Flow Regime Optimization : Identified stable gas velocities for Bubbling, Turbulent, and Fast fluidization to maximize gas-solid contact efficiency.
