Compression analysis for assessment of pellet plasticity: Identification of reactant pores and comparison between Heckel, Kawakita, and Adams equations

- Granular plasticity was assessed from compression analysis.
- The granule plasticity could not be differentiated with global Heckel numbers.
- The voidage Heckel profiles captured the plastic differences to a higher extent.
- The voidage was thus considered as a better descriptor of the reactant pore system.
- Plastic differentiation was enabled using Kawakita and Adams parameters.
