Carbonization of wood tar loaded with nickel and calcium at 900℃ for 1h could afford crystallized mesoporous carbon with good capacities of electromagnetic shielding(EMS) and liquid phase adsorption. Electroconductivity and EMS capacity of the tar-derived carbon were enhanced by washing it with dilute acid to be comparable to those of a commercial electroconductive carbon(acetylene black, named Denkablack). Thus the nickel-catalyzed carbonization was an effective utilization method of wood tar, even though the acid-treated carbon was inferior to Ketjenblack, which is the highest-quality electroconductive carbon, in these functions. This will in turn imply the high practicability of carbonization as a thermochemical conversion means of biomass, because the tar fraction, a low-valued by-product, can be converted into a highly value-added functional carbon.
