Charring (150, 340, 480 degreesC) caused mass loss (7-84%), enrichment of organic carbon (OC) (0-32%), and C-13 depletion (&gt; 150 degreesC). As determined by C-13 MAS NMR, the OC composition of the woods was dominated by (di)-O-alkyl structures, and the chars by alkyl and aromatic structures. With increasing temperature, aromatic structures increased and the chars became more similar, although initial differences in OC concentration and delta(13)C of woods persisted. The BC cluster sizes apparently remained small, pointing towards a low resistance against oxidation. Crown Copyright (C) 2002 Published by Elsevier Science Ltd.
