Wood samples (Japanese cedar, Sugi in Japanese) impregnated with 1 - 10wt% iron were pyrolyzed at 1000°C to study the influences of the impregnated iron on the distribution of the pyrolysis products and the structure of the char. The pyrolysis of wood sample without iron produced about 20% of char and about 32% of tar. In the pyrolysis of the wood samples impregnated with iron, the char yield increased to 35% and the tar yield decreased to a few percent. Both CO and CO<SUB>2</SUB> yields were enhanced by the presence of the impregnated iron. The structure of char produced by pyrolysis of wood sample without iron was amorphous, whereas the turbostratic carbon was formed by the loading of iron. Surface areas of char increased from 30m<SUP>2</SUP>/g for the wood sample without iron to 230 - 270m<SUP>2</SUP>/g for the wood samples with iron.
