16.各種乾留条件で生成した石炭炭化物の細孔パラメータψの算出

抄録

Attempts were made to estimate a reaction rate of coal chars prepared under various pyrolysis conditions using a random pore model (RPM). In order to calculate the pore characteristic parameter ψ in the RPM, Pore structure of char was assessed in terms of mercury porosimetry. The ψ value tended to decrease with higher pyrolysis temperatures and the reaction rate estimated with the ψ value was consistent with the measured rate only in the initial stage of reaction. It was also suggested that there was a different ψ value in/after the middle stage of reaction from that in the initial.
