摘要:
To provide a sustainable method for the synthesis of ammonia from nitrogen by low resources and low energy.The present invention is a method for the synthesis of ammonia by a thermochemical cycle, which uses nitrogen and water as raw materials and uses renewable energy as an energy source. Ammonia is synthesized without auxiliary raw materials by a step of obtaining ammonia by a reaction of nitrogen and a halogenated hydrogen by way of a halogenated ammonium as a cycle that proceeds in a thermodynamic manner, and a step of recycling the byproduced halogen.

摘要:
This invention discloses an improved chemical heat pump system utilizing a reversible decomposition reaction-addition reaction system, wherein a gaseous product is generated by said decomposition reaction. The present system can realize a large coefficient of performance (C.O.P) by introducing into the heat pump system, a separation stage (to separate the decomposition reaction mixture circulating in the system into a gas phase and liquid phase) and then compressing each gas phase and liquid phase separately. By choice of the chemical reaction system, the present system is able to meet various requirements concerning temperatures of the lower heat source and the higher heat source. The present system is superior to conventional systems in reducing attrition of the heat pump apparatus.
