The models were described by a two exponential term expression for the two-tank model in region l (W_0＞100％一d. b.)and a single exponential term expression for the single tank model in region II (W_0＜100％?d. b.) respectively. The two expressions were separately characterized depending on the two regions : In region l, by two mass transfer coefficients, k_<La> for free water molecules and k_<La> for multi?layered adsorbed water molecules and ; in region II, by k_<La> for the mass transfer coefficient of gaseous water. The values of k_<La>, k_<Ia> and k_<Ga> were quantitatively evaluated as a function of W_0 by using the photographic and graphical analysis of the SEM and TPD data. The mathematical equations derived from the tank models using the limited experimental dehydration response curves were sufficiently applied to simulate all the curves obtained at 35?50℃ and W_0＝51?235％?d. b.departmental bulletin paper北見工業大学2000-09application/pdf北見工業大学研究報告1321725https://kitami-it.repo.nii.ac.jp/record/6773/files/32-1-3.pdfjpn
