Coke structural properties influencing coke quality in byproduct and heat-recovery cokemaking, hence accounting for quality differences between these technologies, are investigated. Compared to slot-oven coke, heat-recovery oven coke is less homogenous in quality, as expressed by CSR, pore and carbon structure. The presence of free space above the heat-recovery oven bed promotes swelling of the charge, leading to increased coke surface area toward the top of the bed. While both porous and carbon structure influence quality, pore structure has a stronger influence on CSR in the heat-recovery oven than in the slot-oven, particularly coke at the top section of the heat-recovery oven.
