Objectives
- Determine the high-temperature (1100°C-1550°C) and room temperature compression strengths for four coke blends (2 from pilot oven and 2 from lab coking oven) before and after exposure to reactive conditions
- Develop correlations between the mineralogical, microstructural, and fracture characteristics of the cokes at high temperatures with the evolution of strength after gasification
- Obtain comprehensive understanding of coke degradation arising from reactivity and high-temperature loading reactive conditions for blended cokes from both ovens in order to correlate this behaviour to the constituent coal properties
Outcomes
- Binary blends in lab-scale and pilot ovens showed similar weight losses after gasification while ternary blends showed differences, suggesting latter did not undergo conversion coke conversion
- Strengths are in the similar range of values for all coke sets considering variability, with these values generally being similar or higher than those seen at room temperatures
- Differences in IMDC and RMDC natures in binary and ternary blends are believed to impact on their properties and performance at room and high temperatures
