Transcript

  • 1.  
  • 2. Products:
  • 3.
    • Emission control:
    • - diesel
    • - gasoline
    • Lambda scan at 400 o C
  • 4. Emission control for diesel vehicles
    • Existing technology
    • oxidation catalyst;
    • particulate matter filter (PMF)
    • three way catalyst.
    Working temperature from 250 o C OX PMF TWC
  • 5. Emission control for diesel vehicles An overfilled PMF can damage the engine.
    • Existing technology
    OX PMF TWC has limited capacity and needs regular cleaning and regeneration with an catalyst PMF oxidation HC+CO+NOx+PM CO 2 +H 2 O+N 2
  • 6.
    • Price lower than the complicated three unit system
    • on the market;
    • Adventure’s technology
    The emission control for diesel vehicles comprises of single unit. TWC HC+CO+Nox+PM CO 2 +H 2 O+N 2 OX PMF Adventure TWC
    • NOx trap is incorporated;
    • Working temperature is from 50 o C;
    • Conversion with the catalyst is greater than 99%;
    NOx
  • 7. 100% conversion: Conversion at: 100 100 CO = 100 o C HC = 400 o C 400 200 o C > 99% NOx 200 o C = 94% CO 200 94 200 99 50% conversion: CO = 50 o C HC = 200 o C 50 o C 200 o C 50% conversion: NOx = 150 o C 200 o C
  • 8. Emission control for gasoline vehicles CO 2 +H 2 O+N 2
    • Existing technology
    •  
    •  
    • Pricely Pt and Rh are used in this technology
    NAC TWC First unit : Nitrous oxides (NOx) absorber catalyst (NAC) Second unit consists of three-way catalyst (TWC). HC+CO+NOx+PM
    • Overall conversion : around 90-94%.
  • 9. Emission control for gasoline vehicles CO 2 +H 2 O+N 2
    • Adventure’s technology
    • Activity improves in presence of moisture
    NAC TWC Adventure HC+CO+NOx+PM
    • Very low light-off (LO) temperature: 50 o C
    • Full conversion of exhaust emissions
    One unit with incorporated NOx trap .
  • 10. Emission control for gasoline vehicles Conversion (%) LO (50% conversion)
    • Comparison Adventure / Existing technology
  • 11. Lambda scan at 400 o C
  • 12.
    • Operating temperatures : 540 0 -600 0 C
    • Up to 100% conversion efficiency
    • Good shift activity and steam reforming ratios
    • Additional up to 40% H 2 generated from the steam
    • Activity improves at pressure
  • 13. Steam reforming of gasoline Working conditions: Temperature: 550 o C - 600 o C Pressure : 5 bar. C/S ratio : 1:4.5 *Gasoline from petrol stations 100% conversion of A98* gasoline + 35% H 2 from WGS reaction
  • 14. Steam reforming of diesel Working conditions: Temperature: 500 o C - 540 o C Pressure : 4.5 bar. C/S ratio : 1:4 *Diesel from petrol stations 100% conversion of diesel* + 42% H 2 from WGS reaction
  • 15. Steam reforming of methanol Working conditions: Temperature: 300 o C Pressure : 3.5 bar. C/S ratio : 1:4 100% conversion of methanol + 20% H 2 from WGS reaction
  • 16.
    • Cost of catalyst lower than their alternatives
    • 100% Removal of CO is achieved at 120 0 C
    • Less than 0.1% loss of H 2
    • Selectivity is enhanced in presence of moisture
  • 17. 100% removal (<5ppm) of CO Working t 0 = 120 o C H 2 loss = <0.1%
  • 18. The key to the ecological solution
