This dataset was used to characterize devolatilized wood pellets for fluidized bed applications. The results and the details about the methodology are presented in "Jarolin, K.; Wang, S.; Dymala, T.; Song, T.; Heinrich, S.; Shen, L.; Dosta, M. (2021): Characterizing devolatilized wood pellets for fluidized bed applications. In: Biomass Conversion and Biorefinery." In this work, three types of wood pellets, called Type A (white sawdust pellet from spruce wood), Type B (brown sawdust pellet from foliage and coniferous wood), and Type C (brown sawdust pellet from mixed, unspecified wood types) were characterized after devolatilization. Three different methods for devolatilization were applied: 1. Muffle Furnace (MF) at 900°C 2. Fluidized Bed Reactor (FBR) at 900°C 3. empty fluidized bed reactor with high gas flow rate (HFR) at 900°C 4. empty fluidized bed reactor with low gas flow rate (LFR) at 900°C The raw data from the three main methods for characterization are provided in this repository: 1. compressionTest: Formatted force-displacement measurements of quasi-steady, uniaxial compression tests in the radial direction. The data was used to study breakage behavior. 2. impactTest: Mass loss of the pellets due to impact on a steel plate at different velocities. The mass loss is given after 10 consecutive impacts. In case of breakage, the masses of the fragments are given. The data was used to study resistance to impact and the continuous wear of the pellets. 3. uCT: Micro-computed tomography images from the same pellets before and after devolatilization as well as images of devolatilized pellet for reference. One of the pellets' end-faces was ground into an angle to allow the identification of the orientation. The data was used to study the change in the porosity of the pellets.
