| Outline of Final Research Achievements |
The carbonization behavior of biomass depends on the kind of biomass. It was found that the behavior is roughly surmised by the combining of the behaviors of cellulose, hemi-cellulose, lignin and polypeptone measured solely. The potassium involved in the biomass as ash influenced the carbonization behavior of cellulose, and it was found that the decomposition of cellulose was begun in the lower temperature. The nitrogen content of the char prepared from the biomass containing the protein was very high, and the nitrogen in the char raised the hydrophilicity of the char. As the result, the amount of adsorbed water vapor in the range of lower humidity was increased. Additionally, the potassium chloride in the char promoted the water vapor adsorption in the high humidity range and the ability of the humidity control was improved.
