Wood of the Lead tree (Leucaena Leucocephala) is pyrolyzed in an Iwasaki kiln to produce charcoal with a graphitic-like structure with a surface area of 329 m2/g. The charcoal is ground into 3 different particle sizes (large, medium, and small) and activated with carbon dioxide to produce activated carbon. The structure, morphology, elemental composition, porosity, and functional groups of the activated carbon samples are compared with the charcoal precursor. The larger particle size of the charcoal gives activated carbon with a larger surface area, up to 609 m2/g. In addition, wood vinegar is collected during the pyrolysis at 3 temperature ranges and extracted by n-hexane, diethyl ether, and ethyl acetate. The compositions depend on the collecting temperature. The main components are ketones, organic acids, furan and pyran derivatives, esters, phenols and derivatives, alcohols, and alkanes. [ABSTRACT FROM AUTHOR]
