Abstract

In order to develop new usage of cocoon, production of activated carbon from cocoon was examined. Cocoon plate was prepared by hot-press method for several sheets of flat sheet cocoon. Cocoon plate carbon was carbonized from cocoon plate under the condition of heating at N2 atmosphere. In the purpose of improvement of deodorization for cocoon plate carbon, activation of cocoon plate carbon was performed by using water, CO2-gas or chemicals (ZnCl2, NaOH, K2CO3). Surface area of cocoon plate carbon was increased with using activation agents at 800°C. The largest value of surface area (2186 m2/g) was obtained in the case of K2CO3.
