【 摘 要 】

References(10)Cited-By(2)Pyrolysis of Douglas fir with metal compounds has been carried out to examine the effect of metal compounds on the pyrolysis profiles. The profiles dramatically shifted into lower or higher temperatures by adding some metal compounds. On the other hand, the presence of metal chlorides promoted the decomposition of Douglas fir at low temperature. The metal compounds having high hydrophilicity, by which Douglas fir decomposition was shifted toward lower temperatures, caused an increase in char and a decrease in tar through promoting the cross-linking reaction at low temperature. From these results, it can be said that the control of dehydration at low temperature is an essential factor to achieve high char yield with minimizing tar formation.
