In previous study of Bio-H2 purification, the advantage of 2-step pressure swing adsorption (2-stepPSA) using HAS-Clay and Zeolite A-5 was discussed. These advantages are mainly the abatement of auxiliary power and the sequestration of CO2 gas from syngas. In order to estimate the performance in the dynamic aspect, the simulation software of gPROMS (PSE Inc.) was used. In this program, the input parameters of a thermal conductivity of each adsorbent etc. are necessary. However, so far, the data of HAS-Clay has not been measured at all. Thus, in this study, fabricating the experimental apparatus on basis of a hot wire method, the data was measured, and the result was validated by other data which was measured by another method. Finally, using the experimental data, the dynamic performance of 2-step PSA was simulated.
