Biomass to Biofuels ?
Renewable
? Low H/C ratio? Contains water
─ Corrosion problems? High oxygen content
(aldehydes, acids, cetones)─ Reduced heating value─ Reduced oxidation stability─ Increased acidity
Biomass requires H/C increase, oxygen and Η2Ο removal
Engine performance problems

BIOFUELS-2G Achievements & Potential
Optimal exploitation methodology of waste oils Avoid problematic disposal, 100% conversion to biofuels (Biodiesel-2G,
heavy fuel) Technology of producing highly-sustainable-high-quality
renewable diesel based on waste oils and RES More economic, more reliable, no engine adjustments/changes required
Potential for meeting 9,5% of Greek diesel demand ~223.000 tons or 282.195 m3 Biodiesel-2G
CO2 emissions improvement 14.4-15% (WTW) over conventional market diesel
Technology expanded for integrating waste oils in underling refinery infrastructure (hybrid diesel / Hellenic Petroleum)
