Paper Title:
Properties of Catalytic Filter for the Hot Gas Cleaning
  Abstract

Porous filter was manufactured using cordierite powder and it was loaded with V2O5 catalyst by vacuum impregnation method. The removal efficiency of NOX and simultaneous removal efficiency of NOX /Dust were measured by passing NO and dust through catalystloaded ceramic filter. The cordierite porous filter had the apparent porosity of 61.6%, the compressive strength of 12.3 MPa and the pressure drop of 1200 Pa at the face velocity of 5 cm/sec, at 400oC. NOX removal efficiency of filter loaded only V2O5 catalyst was 80% and it could be improved up to 90% by the acid treatment (which increased specific surface area of filter elements); then this result is equal to the removal efficiency of the commercial V2O5/TiO2 catalyst, which was used at SCR(Selective Catalytic Reduction) process. Dust & NOX simultaneous removal efficiency of filter loaded V2O5 catalyst was about 99.6% of dust and 90% of NOX. Crack generated by thermal shock or pressure was not found. We found that catalytic cordierite filter is good candidate for simultaneous removal of particulate and hazardous gas from this result.
