Abstract: This paper briefly analyses the resource situation、application and consumption structure of rhenium.As the areas of consumption are concentrated,the paper uses the method of sector demand forecasting to analyze the future rhenium demand of world and China by analyzing the future trends of the main industries of aviation engines and catalysts.It is expected that the rhenium demand will continue to increase of world and China,and China rhenium maximal demand will have reached 40 tby 2030which is about 1/5of the world.Due to the low level of domestic rhenium supply and support capabilities,the suggestion to protect the security of China rhenium supply is to increase the mine production of rhenium,form the industry of rhenium scrap recovery and establish the strategic reserve mechanism of rhenium.
