High cell density Layered SCR catalyst

With the government funded Green Innovation Company Support Project (so called Green New Deal Project), the product currently under commercialization process is the high density layered SCR catalyst (NTL-65C) for removing nitrogen oxides from LNG power plants. In this development the cell density is increased from 45 cpsi to 65 cpsi, but the thickness of inner wall is maintained at the level of 0.3 ㎜ to maximize NOx removal and minimize differential pressure drop for applications.

  • Product Usage
