Study on the generation system by thermal cycle of gas hydrate using a carbon cloth supported catalysts

Abstract

In cold regions, because the heat demand is high in winter, greenhouse gas emission is an issue. In this study, we propose a new power generation system using a CO2 hydrate. This system uses the pressure variation properties of the CO2 hydrate under temperature changes. However, since the production speed of the CO2 hydrate is basically slow, efficiency of heat cycle of the system is decreased. Before now, increase in gas absorption of the CO2 hydrate is confirmed by using mixed powder of hematite and graphite (afterward iron oxide catalyst). Increase in gas absorption of the CO2 hydrate contributes to improvement for the efficiency of heat cycle of the CO2 hydrate. The subject of the present research devise improvement of the contact probability of three-phase interface of the CO2 hydrate for further improvement of gas absorption by microstructural carbon cloth support iron oxide catalysts.
