Moisture sorption characteristics of switchgrass and prairie cord grass

- Moisture content (MC) plays an important role in the bio/thermochemical conversion of feedstocks into energy.
- Knowledge of the relationship between air relative humidity (RH) and feedstock MC is essential for drying and storage.
- Equilibrium MC at different equilibrium RH and temperatures were determined and fitted with five-three parameter models.
- Modified Halsey emerged as the best model followed by modified Oswin model for switchgrass and prairie cord grass.
