It is essential to efficiently utilize recycled resources for the establishment of a sustainable society. For thermal power plants, the reduction of the amount of wasted valuable and useful resources is also required. Since De-NOx catalysts that detoxify nitrogen oxides (NOx) in combustion exhaust gas contain expensive metals such as titanium and tungsten, there is strong desire for technology to reuse them instead of discarding them after use in power plants. Therefore, Mitsubishi Power, Ltd. (Mitsubishi Power) has developed a technology for reusing De-NOx catalysts used for coal and heavy oil-fired exhaust gas. The technology for reusing spent catalysts not only reduces the amount of waste and the waste disposal costs of our customers, but also contributes to securing rare recycled resources and preserving the global environment.
