Abstract
Carbonization of wood waste contributes to prevention of global warming through carbon fixation and the obtained charcoal can be effectively used for environmental purification. However it is not expected the charcoal obtained by mere carbonization has various uses. In this study, thermal decomposition of chips of Japanese cypress soaked in Ca solution and absorption properties of obtained charcoal for hydrogen chloride gas were investigated to develop a novel functional charcoal. Ca(OH)2 was used as Ca source due to less environmental load and easy handling. Ca-impregnated chips were heat-treated in an electric muffle furnace at temperatures between 600 and 900°C. The fine calcite crystals were dispersed homogeneously on the surface of tracheids in the heat-treated samples. The measurements of absorption properties for hydrogen chloride gas revealed that the absorptive ability and durability of these samples were higher than those of the conventional materials. From these results, it was suggested that an acidic gas absorption material with high reactivity could be prepared simply by the thermal decomposition of wood waste soaked in Ca solution.
