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 N 2 + O2 + H2O + NOx + (Fly ash) + (SOx)
Normally the moral ratio of NOx and NH3 is 1 to 1.(NOx : NH3 = 1 : 1)

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

Comparison between CATCERA and Honeycomb/Corrugate – Operating Principle
Notes :
1. Composition of exhaust gas differs from
fuel types.
2. 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.
3. Ammonia is oxidized to NOx.
4. Lower ammonia concentration
increases NOx Concentration.
5. Ammonia concentration is lower than
regulation, fly ash is captured by
CATCERA and NOx conversion ratio
will be up to 98%.
