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)

BIOFUELS-2G & PPPs

Waste oils recycling─ Public awareness (local & national authorities,

schools, NGOs)─ Collection & transportation (local authorities,

SMEs or large enterprises) Waste oils conversion to fuel

─ Waste oils pretreatment (SMEs or large enterprises)

─ Conversion to fuel (SMEs or large enterprises)
