Powdered softwood and hardwood loaded with 3 wt % iron by aqueous impregnation were carbonized at 850℃ for１h to in detail examine both fuel properties of light tar distilled off at below 500°C and gaseous components evolved at above 500°C and the quality and capacity of crystallized mesoporous carbon as electro-conductive filler and liquid phase adsorbent for macromolecules. Comparison with earlier developed nickel-catalyzed carbonization at 900°C for 1 h was adequate for demonstrating the promising commercial operation of the above iron-catalyzed carbonization as wood refinery process for coproduction of fluid fuels and functional carbon. In this connection, not iron nitrate but iron acetate was recommended as the catalyst precursor in terms of environmental load. Furthermore, the aptitude of Fe-char prepared at 500℃ for electrode carbon of electric double layer capacitor as a new application was checked after activation with KOH at 700-900℃. Because ultrafine iron particles existed as quantum dot in this char made mesoporosity develop effectively, the activated Fe-char exceeded commercial carbon in the performance. Thus, this Fe char-derived electrode was considered to be practical.

以针叶木和阔叶木为原料，通过水溶液浸渍法负载3wt%的铁，在850℃下浸渍1h，考察了500 ℃以下馏出的轻焦油和500 ℃以上挥发出的气体组分的燃料性质，以及结晶介孔炭作为导电填料和液相大分子吸附剂的质量和性能。与早期开发的在900°C下持续1小时的镍催化碳化的比较足以证明上述铁催化碳化作为用于联产流体燃料和功能性碳的木材精炼工艺的有前景的商业操作。在这方面，就环境负荷而言，不推荐硝酸铁而是推荐乙酸铁作为催化剂前体。此外，还考察了500℃制备的铁炭经700-900℃ KOH活化后，作为双电层电容器电极炭的新用途。由于超细铁粒子以量子点的形式存在于活性炭中，使活性炭中孔得以有效发育，因此活性铁炭的性能优于商品炭。因此，认为该Fe炭衍生电极是实用的。
