Effects of Heating at Lower Temperature on Water Adsorption Behavior for Wood
Masanobu SHIGA and Takato NAKANO
Abstract:Isotherm curves of wood samples heated at lower temperatures 150, 175, and 200°C for various periods were examined on the basis of the characterization theories of adsorption, Hailwood and Horrobin theory, Dubinin-Radushkevich theory, and Neimark theory. The adsorption properties were characterized by the parameters of their theories. Their properties without the fractal dimensionality were presented by weight change regardless of heating temperature and had the transition point at weight change = -0.2. Key Words:Heating, water, adsorption, Fractal dimensionality, Dubinin-Radushkevich theory, Hailwood & Horrobin theory
