| Abstract Scope |
Steelmaking industry is one of biggest sources of anthropogenic greenhouse gases emissions. The main source of energy for reduction of iron ores is carbon from coking coals. Growing capacities of renewable energy generation will gradually enable economical production of hydrogen with the help of water electrolysis. However, fluctuating nature of renewable energy generation poses a question of reduction agent for ironmaking in the periods of time when hydrogen production becomes non-economical. One of the solutions could be the use of natural gas. The scope of the GISH project is to evaluate and implement semi-industrial technology of the hydrogen and natural gas-based steelmaking. Arizona State University team is responsible for the experimental measurement and modeling of kinetics of the iron ore pellets reduction in various H2-CO gas mixtures. A new enhanced model of single pellet reduction is created in COMSOL Multiphysics. Progress of the project and experimental results is discussed. |
