CPC Corporation has developed technologies for recycling both flat and honeycombshaped denitration catalysts, achieving an activity recovery rate of over 80%. These technologies not only reduce costs for businesses but also decrease waste and the carbon emissions associated with the production of new catalysts.
Nitrogen oxides are major air pollutants primarily generated from industrial combustion furnaces, boilers, and vehicles. Selective Catalytic Reduction (SCR) is the most widely used denitration technology. CPC Corporation is actively developing related technologies and recycling solutions.
Denitration Catalyst Recycling
In 2022, CPC Corporation successfully developed a recycling technology for flat denitration catalysts. The recycled catalysts exhibit an activity recovery rate of over 80% and are already being used effectively in the China Steel Power Plant.
In 2023, CPC Corporation further advanced this technology by developing a recycling process for honeycomb-shaped denitration catalysts. This process involves recycling old honeycomb-shaped catalysts removed from CPC facilities and reusing them in the plant. This technology not only extends the lifespan of denitration catalysts but also significantly reduces waste generation.
Benefits
- The cost of recycled flat and honeycomb-shaped denitration catalysts is only 60-70% of the cost of new catalysts.
