X-ray microcomputed tomography data collected at the advanced light source beamline 8.3.2 of almond shell and softwood biochars hydropyrolyzed at 500 C and an almond shell biochar gasified at 800 C. Gross morphological differences among AS500, AS800 and SW500 were visualized by X-ray micro-computed tomography (X-ray microCT) at the Lawrence Berkeley National Laboratory Advance Light Source on beamline 8.3.2 using a beam energy of 21 KeV. 1025 projections were acquired using continuous tomography mode with a 4x objective, for a final pixel size of 1.7 µm. Images were reconstructed using gridrec methods via TomoPy and Xi-CAM . Image analysis was completed in Dragonfly, a 3d image analysis software free for non-commercial use (Object Research Systems, Canada).
