1. 2. Products:
2. 3. <ul><li>Emission control: </li></ul><ul><li>- diesel </li></ul><ul><li>- gasoline </li></ul><ul><li>Lambda scan at 400 o C </li></ul>
3. 4. Emission control for diesel vehicles <ul><li>Existing technology </li></ul><ul><li>oxidation catalyst; </li></ul><ul><li>particulate matter filter (PMF) </li></ul><ul><li>three way catalyst. </li></ul>Working temperature from 250 o C OX PMF TWC
4. 5. Emission control for diesel vehicles An overfilled PMF can damage the engine. <ul><li>Existing technology </li></ul>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
5. 6. <ul><li>Price lower than the complicated three unit system </li></ul><ul><li>on the market; </li></ul><ul><li>Adventure’s technology </li></ul>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 <ul><li>NOx trap is incorporated; </li></ul><ul><li>Working temperature is from 50 o C; </li></ul><ul><li>Conversion with the catalyst is greater than 99%; </li></ul>NOx
6. 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
7. 8. Emission control for gasoline vehicles CO 2 +H 2 O+N 2 <ul><li>Existing technology </li></ul><ul><li>  </li></ul><ul><li>  </li></ul><ul><li>Pricely Pt and Rh are used in this technology </li></ul>NAC TWC First unit : Nitrous oxides (NOx) absorber catalyst (NAC) Second unit consists of three-way catalyst (TWC). HC+CO+NOx+PM <ul><li>Overall conversion : around 90-94%. </li></ul>
8. 9. Emission control for gasoline vehicles CO 2 +H 2 O+N 2 <ul><li>Adventure’s technology </li></ul><ul><li>Activity improves in presence of moisture </li></ul>NAC TWC Adventure HC+CO+NOx+PM <ul><li>Very low light-off (LO) temperature: 50 o C </li></ul><ul><li>Full conversion of exhaust emissions </li></ul>One unit with incorporated NOx trap .
9. 10. Emission control for gasoline vehicles Conversion (%) LO (50% conversion) <ul><li>Comparison Adventure / Existing technology </li></ul>
10. 11. Lambda scan at 400 o C
11. 12. <ul><li>Operating temperatures : 540 0 -600 0 C </li></ul><ul><li>Up to 100% conversion efficiency </li></ul><ul><li>Good shift activity and steam reforming ratios </li></ul><ul><li>Additional up to 40% H 2 generated from the steam </li></ul><ul><li>Activity improves at pressure </li></ul>
12. 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
13. 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
14. 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
15. 16. <ul><li>Cost of catalyst lower than their alternatives </li></ul><ul><li>100% Removal of CO is achieved at 120 0 C </li></ul><ul><li>Less than 0.1% loss of H 2 </li></ul><ul><li>Selectivity is enhanced in presence of moisture </li></ul>
16. 17. 100% removal (<5ppm) of CO Working t 0 = 120 o C H 2 loss = <0.1%
