Research Abstract

Cedar (Cryptomeria japonica D. Don) bark is a troublesome waste matter in the forestry because it takes long time to rot if left on the ground. On the other hand, activated carbons, although they have been widely used already, are still object of active research because they show large variety of performance depending on starting materials and preparation conditions. This work aimed at clarifying the suitable conditions for preparation of activated carbon from Japanese cedar bark.
(1)Firstly, the carbonization behavior of cedar bark in inert atmosphere was investigated. The process was monitored by optical microscope, surface area and porosity measurement, and other instrumental analysis, and the condition in which the fibrous structure of the cedar bark was largely retained was found out.
(2)Using the carbonaceous material thus obtained as a starting material, the condition of the activation in the carbon dioxide atmosphere was investigated, and an activated carbon having characteristics comparable to commercial ones was obtained.
(3)The carbonization and the activation of another biomass waste produced in the local area, i.e. rice straw, chaff, and others, were also studied, and it was found that cedar bark is most suitable for raw material of activated carbon among the materials studied.
(4)The mass transfer velocity was evaluated by a pulse chromatography adapting methane as a probe in helium carrier. The sample prepared from cedar bark showed somewhat higher rate than conventional activated carbon.
