The higher volatile content of biomass [22], [23] may affect fluidity during the plastic phase of the cokemaking process, ultimately leading to biocokes with high coke reactivity index (CRI) and low coke strength after reaction (CSR) compared to conventional cokes [24]. The feed size also affects the mechanical properties of the biocoke.
