Research Abstract

Test fabrication of honeycomb catalyst and adsorbent was attempted, of which performance was experimentally investigated. Promising catalyst and adsorbent were found. With regard to promising catalysts, isotope effects were examined using deuterium and tritium. The effect of coexistent water vapor on catalytic activity was investigated as well. In terms of promising adsorbents, adsorption characteristics were thoroughly examined.
