The structure of carbon nanotubes is particularly a tube composed of a hexagonal network similar to graphite. The unique nano-hollow structure and closed helical structure with different topological configurations make it have a lot of special excellent properties. Such as good electrical conductivity, heat resistance, high mechanical strength, corrosion resistance, self-lubricating and biocompatibility, etc.

SCR denitration technology is a necessary means for power plants to achieve ultra-clean emissions. Catalysts, as a core part of SCR denitration technology, lose their activity due to wear or blockage during operation. Some of the regenerable catalysts can be reused after regeneration, while the catalysts that cannot be regenerated face the situation of rational utilization and disposal.

A large amount of blast furnace slag will be discharged in the process of blast furnace ironmaking. If not properly treated, it will occupy land, pollute the environment and cause waste of resources. Blast furnace slag contains valuable metals such as titanium, silicon, aluminium and calcium. It can be separated, extracted and processed into chemical products by appropriate methods. It can make rational use of industrial waste resources and solve environmental pollution problems.

Nitrogen oxides (NOx) are important atmospheric pollutants that can cause environmental problems such as acid rain and photochemical smog, as well as direct damage to the human respiratory system.  In addition, it also has an important contribution to the increasingly serious ash pollution in our country.  Therefore, effective control of NOx emissions is a major strategic need in China.
