项目摘要

Realistic design and chemical processes of georeactor in geothermal environment were proposed as a advanced direct utilization of geothermal energy. Material processing type, composed of high aspect ratio double and /or multiple tube reactor, could be applied to chemical reaction within the reactor installed in the drill hole, and the other type is steam generator which supplies hot water and steam for chemical reactor constructed on the surface. Adequate chemical processes for the georeactor require mild reaction condition and wide allowance of operating condition because the georeactor is applied in uncontrollable natural resources.Hydrogen generating system, produced from hydrogen sulfide with high performance photocatalysis, was examined as a case study of the georeactor. Hydrogen generation by solar energy from hydrogen sulfide and recycling of waste sulfur and its compounds using geothermal energy, which is environmental friendly energy supply system in the future. The most impor … More tant factor for designing georeactor is not hard-ware of rector but soft-ware of chemical process. Georeactor shows distinctive properties such as sustainable chemical reactor, environmental harmony friendly system. However, the georeactor has other disadvantages, for example extremely high aspect ratio (long tube reactor), and temperature and pressure conditions can not be controlled actively that depends natural geothermal conditions. So that, precious chemical processes which require high sensitive control of temperature, pressure and chemical reaction behavior was not suitable for georeactor, however specific chemical processes which allow wide range of temperatures and pressures can be expectedas reaction system for georeactor.In this study, we focused on sulfur -water interaction, particularly on and waste elemental sulfur which can be converted to useful sulfur resources for hydrogen production using high performance optical catalysis. We promote other chemical processes for constructing geotreactor. Less
