  2. Characteristics of CATCERA -. CATCERA : Ceramic Filter-Catalyst Composite -. Maximized Filtering Area with Variable Shapes -. High Reacting/Filtering Efficiency by 3-dimensional Tunnel Structure -. Excellent Porous Shape with Low Pressure Drop -. Excellent Chemical/Wear Resistance -. Controllable Porosity -. More Than 50% of Porosity to be Light Weight -. High Strength for High Temperature/Pressure -. Multi-Function in DeNOx SCR and Filter -. Ease of Backflushing -. Excellent Cost-Benefit -. Up to 2m Length [ Cross Section ] [ Side View ] [ Rectangular Shape ] [ Hollow Cylinder Shape ]

  3. Various Shape of CATCERA and Working Principle Punched Plate CATCERA Exhaust gas(N2 + NOx + Fly ash + SOx) Ammonia gas(NH3) Fly ash Purified exhaust gas(N2 + SOx) Air pulse Note : Composition of exhaust gas differs from the fuel. Normally N2 + O2 + H2O + NOx + (Fly ash) + (SOx) Normally the moral ratio of NOx and NH3 is 1 to 1.(NOx : NH3 = 1 : 1)

  5. CATCERA SCR Selective Catalytic Reduction (SCR) • Mechanism : Using same mole concentration with NH3 Specialty of NCI’s Product • High Temperature Stability : up to 1,000oF • Rutile phase synthesis on low temp. less then 200oF CATCERA(Ceramic Filter-SCR Catalyst Composite) • Pore Size : ~ PM10(up to 10 microns) • High Porosity : ~90% • Relatively Low Cost : Comparable teflon bag filter • Variable Shape • Substitutable Honeycomb with using SCR Catalyst • Pressure Drop : Up to 10cmH2O @ 10cm3/sec/cm2 air DPF/DOC • Soot Removal by Direct Catalytic Oxidation • Relatively Low Cost • Variable Shape • Simultaneous Removal of Soot and NOx

  6. Applicable Area of CATCERA • CATCERA is useful(or effective) on nearly all high temperature processes where the hot gas may contain smoke, fume or dust. It covers a broad range of application including; • Pre-Purification of CO2 removal system • Waste incineration • Thermal power plant, Coal-fired power plant • IGCC(Integrated Gasification Combined Cycle) • Pyrolysis • Chemical processing • Metals smelting • Glass melting • Industrial boiler • Cement plant • Diesel exhaust emission control facility • Dust collector, Soot collector CATCERA

  7. Comparison between CATCERA and Honeycomb/Corrugate – Operating Principle • Notes: • Composition of exhaust gas differs from fuel types. • Ammonia concentration is higher than regulation, and NOx conversion ratio will be up to 85%. Because of fly ash, surface of honeycomb/corrugate is covered by alkaline oxides such as CaO, MgO, etc in one year to degrade SCR catalytic function for coal fire boilers. • Ammonia is oxidized to NOx. • Lower ammonia concentration increases NOx Concentration. • Ammonia concentration is lower than regulation, fly ash is captured by CATCERA and NOx conversion ratio will be up to 98%.
