Japanese larch wood loaded with nickel (1%-4%) alone or with nickel and calcium (0.25%-1.5%) was carbonized at 800°-900°C for 0-120min with a heating rate of 5°-20°C min-1 in a helium flow of 5.8-46.4 ml STP cm-2 min-1 to examine the influence of these variables on the crystallization of carbon (the formation of T component) and the development of mesoporosity. From the obtained results, reaction conditions suitable for effective production of carbon with the dual functions of adequate electroconductivity and adsorption capacity in liquid phase were established, thereby explaining the factors that govern the process. It was also confirmed that mesopore having a diameter of about 4 nm was selectively produced at the cost of specific (BET) surface area in parallel with the formation of T component. This result provided good insight into how the simultaneous dual function could be realized.
