摘要：
Pyrolysis experiments in a thermogravimetric analyser and in a muffle furnace: were carried out with spruce and beech wood. The particle size of the samples of spruce wood was varied in the range 0.5-20 mm and the heating rate was varied in the range 5-60 K/min. Additionally, drop-in experiments in the muffle furnace were carried out with both spruce and beech wood. These experimental data were compared with the results from calculation of pyrolysis of 'large' particles with the simulation program PARSIM. Agreement could only be obtained when the tar decomposition outside of the particle was taken into account. The pre-exponential factor and the ultimate Yield for cracking of tar from beech wood are given. (C) 2002 Elsevier Science B.V. All rights reserved.
