Objectives
- Understand the impact of biomass addition on changes in the microstructural, macrostructural, and microtextural features of cokes
through different characterisation techniques - Analyse the physical, microstructural, and interfacial bonding features of the textural components in the coke-biochar blends through
fractography and microtextural analysis - Comparison of performance of these biocokes with standard coke quality indicators
Outcomes
- Studies showed that the particle size of the biochar had a huge impact on successful integration of the char particles into the coke matrix
- Strength of cokes at room temperature as well as standard coke quality metrics (CSR, CRI, I 40) were affected by the particle size of the biochar and the degree of integration into the matrix
- High-temperature strengths were variable and were more linked to high-temperature changes to the coke microtexture and mineralogy
