High Electro-conductivity of Wood Char Obtained by Iron-catalyzed Carbonization
Introduction Nickel-catalyzed carbonization of wood at 900℃ can afford crystallized mesoporous char carbon with high electro-conductivity and good liquid phase adsorption capacity for rnacromolecules. This catalytic carbonization has another advantage of the efficient production of hydrogen-rich gas together with the upgrading of oil fraction. The successful simultaneous conversion into functional material and fluid energies will make the process industrially attractive. On the other hand, recently examined iron-catalyzed carbonization at 850℃ turned out to be more suitable for producing the functional wood carbon. The present study describes why iron-loaded char prepared at 850℃ could have higher electro-conductivity than nickel-loaded one obtained at 900℃. The favorable effect of subsequent pulverization followed by soaking in acid, which are post-treatments to be incorporated into the manufacturing process of carbon products, is also explained and discussed.
