Objectives
- Develop an understanding of the impact of H2-rich blast furnace operations on coke performance in comparison with current typical operations
- Analyse the effects of gasification in different atmospheres on the extent of degradation of the cokes through determining the changes in mechanical strengths at room temperature and high temperature
- Provide a qualitative description of changes in microstructural and mineralogical characteristics of the cokes after gasification under different atmospheres
- Provide similar description of the variations of coke characteristics and strengths at room temperature and at high-temperatures) under blast furnace conditions
Outcomes
- The rank of the coal used for coke production has an impact on the coke quality and performance under blast furnace conditions
- Room temperature strengths under different gasification conditions were quite similar indicating that gasification conditions did not impact on the strengths
- high-temperature strengths were higher than those observed at room temperature; moreover, there was no clear correlation with the gasification condition or the coke rank
