The kinetics of wood pyrolysis into gas, tar, and char was investigated in the range of 300 to 400/degree/C at atmospheric pressure. An experimental system which facilitates the monitoring of the actual sample temperature, collection of gas and tar, and measurement of the sample weight loss as a function of time was developed. It has been found that, in the range investigated, wood decomposition into gas, tar, and char can be described by three parallel first-order reactions as suggested by F. Shafizadeh and P.P.S. Chin. The activation energies for these reactions are 88.6, 112.7 and 106.5 kJ/mol, respectively and their frequency factors defined on a mass basis are 8.61*10/sup 5/, 2.47*10/sup 8/, and 4.43*10/sup 7/ min/sup -1/. 12 refs.
