  1. SUSTOIL, Foggia- Italy, Friday 24 April 2009 Levulinic acid as platform chemical from oil plant straw presented by: Prof. Dr. Birgit Kamm Scientific Director, Research Institute biopos e.V., 14513 Teltow-Seehof, Germany, kamm@biopos.de and Brandenburg University of Technology Cottbus

  2. SUSTOIL, Foggia- Italy, Friday 24 April 2009 Levulinic acid as platform chemical from oil plant straw (involved in WP 1, WP 2) • Content: • Fractionation from whole oil plants • Yields of straw from oil crops • Model for Production of Platform Chemicals • (Levulinic acid) • Acidolyse of carbohydrates • Production and Application • 4. LA-derived transport fuels • 5. Next steps

  3. 1. Fractionation of whole crop oil plantExample: rape chain flow chart source: ifeu / supplement: biorefinery.de GmbH

  4. SUSTOIL, Foggia- Italy, Friday 24 April 2009 2. Yields of straw from oil crops • Harvesting rape plant: 7 tons / ha • (2) Fractionation • Seed: 3 tons/ ha • Straw: 4 tons/ ha • 2 tons straw left in field • 2 tons straw go to processing • (3) Press cake fractionation • Crude fibres from rapeseed: • 10,3 % (on d.m.) • Crude fibres from sunflower-seed: • 17,3 % (on d.m.)

  5. 3. Model for Production of platform chemicals (such as levulinic acid)  Kamm, B.; Gruber, P.R.; Kamm, M.; Biorefineries, Industrial Processes and Products, Wiley-VCH, 2006

  6. Acidolysis of carbohydrates Levulinic acid + ester use: cosmetics industry, odoriferous substance, solvent, textile printing

  7. Demonstration Plant in EuropeBiofine ProcessCaserta /Italy3000 t/day The feedstock is hydrolysed with 1-5% mineral acid in two reactors. The first has a temperature of 210-230°C and a residence time of 13-25 seconds. Hydroxymethyl furfural is produced and goes to a second reactor where it is hydrolysed further at 195-215 °C for 15-30 minutes to produce levulinic acid from cellulose.

  9. 4. LA-Derived Transport Fuels Methyltetrahydrofuran (MTHF) is produced via the catalysed hydrogenation of LA to g-valerolactone (GVL), which, on further hydrogenation, yields 1,4-pentanediol and MTHF in high yield (92% theoretical  ~110 litres MTHF for 100 litres of LA).

  10. LA-Derived Transport Fuels ETHYL LEVULINATE An ester of LA that is used as an oxygenate diesel additive. Allows diesel and ethanol to mix. Up to 20% of total volume in regular diesel engines, no adverse effects on performance. High oxygen content and lubricity allows a cleaner burn.

  11. 5. Next steps Evaluation of further product lines and applications based on levulinic acid Estimation of potential market volumes of platform chemical Proposals for further research and development in Europe
