| Abstract: | This study presents a comprehensive assessment of the morphology and porosity of microstructured charcoal using a combination of scanning electron microscopy (SEM), computed tomography (CT), and mercury intrusion porosimetry (MIP) methods. SEM analysis revealed a parallel arrangement of tube-like structures interspersed with smaller pores, confirming the presence of fibrous formations. MIP evaluation was conducted in two research series. MIP results identified macropores as the primary contributors to mercury intrusion; however, a minor volume of mercury also intrudes to the mesopores. The total pore area was determined to range between 70.7 and 88.5 m2·g−1, with porosity values of approximately 58.0–62.4% across different experimental series. These variations highlight the heterogeneous nature of the sample. Additionally, the uniformity of the charring process during dry wood distillation was indicated by wall thickness measurements, which ranged narrowly from 5.7 to 25 µm. [ABSTRACT FROM AUTHOR] |
