1. KMUTT Energy Forum ครั้งที่ 6 เชื้อเพลิงเอทานอล ED95 คุณณัฐชาติ จารุจินดา ประธานเจ้าหน้าที่ปฏิบัติการกลุ่มธุรกิจปิโตรเลียมขั้นปลาย   บริษัท ปตท. จำกัด (มหาชน) 5 เมษายน 2556

2. Outline • EU Roadmap Greenhouse Gas Emission • Application of Ethanol Fuel in Sweden • What is ED95 ? • ED95 Engine • ED95 in Thailand and PTT-Scania Collaboration Progress • Comparison between normal diesel / NGV and ED95

3. 2005-2020: Minus 10% EU Roadmap – Greenhouse Gas Emissions l2020 l2000 l2010

4. Ethanolfrom sugar cane< 90% Synthetic dieselfrom biomass< 80% BiodieselFAME, RME, etc. < 70% Biogasfrom waste, sewage < 90% Sustainable Transport – Available Biofuels Best Case CO2 reduction These fuels are available today

5. Fuel Alternatives

6. Application of Ethanol Fuel In Sweden In heavy duty diesel application, the most applicable of ethanol fuel with high efficiency is ED95. E85 is, in general, not match with diesel application due to extremely high octane number. Source: http://en.wikipedia.org/wiki/Biofuel_in_Sweden Ethanol for Dedicated Compression Ignition Engines (ED95)

7. What is ED95 fuel ? ED95 is a pure ethanol fuel with additives for diesel engine adapted for ethanol The composition of ED95 fuel : Additives : • Ignition improver • Denaturant (by law) • Corrosion inhibitor • Lubricity additive

8. Ethanol specification comparison

9. Properties of ED95 ED95 Diesel Density(kg/m3) 810-830810-820 Flashpoint(°C) 12>56 Cetane number ~10>50 Biofuel (vol-%) >95<7 Energy content (MJ/kg) 24.744.5 Energy content (MJ/litre) 20.535.6 Handling and properties of ED959  ED95 is a stable fuel with long shelf life  Must be handled as gasoline for safety reasons

10. ED95 fulfils the Euro 5 emission standard and EEV

11. Scania ED95 Engine 3rd generation diesel-ethanol engine Based on the 9-litre Euro 4 diesel engine 270 hp, 1200 Nm Euro 5 and EEV Best available environmental standard 9-litre diesel engine 270 hp, 1200 Nm Thermal efficiency Ethanol up to 43% Diesel up to 44% Proven technology Cost efficient way to replace diesel

12. ED95 Engine • Ethanol resistant fuel system (unit injectors) • Increased fuel injector size (+75% at equal pressure) • Very high compression ratio: 28:1 • Ethanol compatible engine oil • Reduced service interval • Short route EGR, with venturi • to reduce NOx emissions (Euro 5 diesel EGR levels) • Oxidation catalyst • eliminating CO and HC emissions ED95 piston 28:1 HSD piston 17:1

13. Scania’s commitment to sustainabilityVehicles, fuels, infrastructure…

15. ED95 Project in Thailand January 23rd 2011 at Bangkok 9 Partners

16. ED95 Project in Thailand

17. ED95 Project in Thailand PTT supported ED95 station (fuel system, pump, tank and dispenser) Additive imported from Brazil

18. ED95 Station 1. Storage EtOH and additive separated , mixed when fill in bus or truck EtOH tank Additive tank 2. Storage finish ED95 (mixed EtOH and additive in tank) ED95 tank

19. PTT & Scania Siam Collaboration Project on ED95 Working Schedule • Objective : • To develop ED 95 formulation by using PTT ‘s additive • Testing & Evalutaion by Scania : • Engine Test : modified single cylinder ( CR = 28:1 ) • Performance evaluation : • Ignition delay • Combustion Stability • Conclusion : • Scania approve PTT ED95 formulation

20. Comparison between NGV and ED95 for heavy duty vehicles * Reference : KMIT ED95 Project

21. Comparison between Diesel and ED95 for heavy duty vehicles * Reference : KMIT ED95 Project

22. Emission : ED95 vs CNG vs Diesel All emission emitted by ED95 bus comparing to diesel is totally less than diesel, while the PM and CO are higher than CNG bus. แหล่งที่มา: ข้อมูลจาก รายงานประจำปี 2554 กรมควบคุมมลพิษ
