| Research Abstract |
Following studies were carried out in the period of this study.
(1) Reaction Kinetics of Gaseous Reaction in the Fixed Bed of Reduced Iron Pellets. It was found that catalytic activity of reduced iron pellet was affected by the conditions of production temperature, kinds of reducing gas and atmospheric temperature.
(2) Development of Measuring Method of Catalytic Metal Surface Area. In order to clarify the reaction mechanism of catalytic gaseous reaction and to establish of rate equation, it needs to evaluate the surface area of catalyst. The catalyst dont always show smooth surface not only porous catalysts but also metal catalysts. Therefore, catalyst surface area cant determine from the shape of catalysts. In this study, it was developed measuring method of catalytic metal surface area by electrolytic solution method. It was found that the surface area of Ni catalyst pellet and Fe catalyst by means of this method were about 50 % larger than the surface area obtained from shape.
(3) Reaction Kinetics of Gaseous Reaction in the Fixed Bed of Catalytic Metals. Rate of water gas shift reaction at high pressure and high temperature were measured in the presence of Ni and Fe catalysts respectively. Rate equation and rate constant were determined from the data obtained. Available surface area was evaluated from the value measured by electrolytic solution method.
(4) Summarization Results obtained in this study were summarized.
