To access the final edited and published work see https://pubs.acs.org/doi/abs/10.1021/acs.energyfuels.6b02112Moringa oleifera seed shells exhibit a unique structure of cross-linked sub-microfibers (0.5-1.5 μm diameter) with a well-connected macroporous network. Controlled pyrolysis (500-800 °C) and cyclic activation of the precursor provided a porous carbon material with a structure that minimizes mass-transfer constraints. Under both slow (10 °C/min-1) and flash pyrolysis, the structure was preserved, while a significant microporosity was developed. By flash pyrolysis (700-800 °C), a material with enhanced characteristics for potential application as a molecular sieve (SDA = 450-470 m2 g-1, and SBET = 5 m2 g-1) was obtained. Cyclic activation of carbonized shells, consisting of an oxygen chemisorption stage (180 °C) followed by a desorption stage in an inert atmosphere (450-900 °C), resulted in a controlled development of microporosity upon successive activation cycles. After 10 activation cycles, respective SDA and SBET values of 1172 and 761 m2 g-1 were obtained. Higher development of the surface area and a wider distribution of micropores was observed when the desorption stage was carried out at 900 °C. The development of the surface area was achieved at low burnoff (22-33%), thus preserving the structure of the material. Thanks to its unique structure, the material obtained exhibited enhanced characteristics for gas sorption as a result of diminished mass-transfer limitations, assessed through the kinetics of carbon dioxide adsorption runs at ambient conditionsThe authors greatly appreciate financial support from the Spanish Ministerio de Economía y Competitividad (CTQ2012-32821)American Chemical SocietyDepartamento de Ingeniería QuímicaFacultad de CienciasUAM.
