FBC Key Benefits – Performance

  • Does not require special Ultra Low Sulphur Diesel

  • Works with a wide range of engine size and age

  • No secondary emissions of un-wanted NO2

Allows for significant reduction (up to 90%) in base Pt catalyst used on the retrofit device

Continual replenishment of the catalyst during operation life ensures long term device durability and reliable service.

FBC

Catalytic Oxidation of Diesel Particulates-carbon

fraction Carbon is oxidised by:

Temp

Oxygen C+O2 CO/CO 2 M a n y m e t a l s p r o m o t e C + O 2 r e a c t i o n but have no reaction with NOx

550+ C 420-600 C

NO2

C+NO2

CO/CO +NO

2 2

Platinum promotes 2NO +O = 2NO2

280-420 C

NO (+02) 2C+O2+2NO

2CO2+N2

280-600 C

Reaction is catalyzed by Platinum +cerium

Platinum + cerium oxidizes both the carbon and hydrocarbons (SOF) present in the exhaust at temperatures as low as 200C
