  1. Technology for 2nd Generation Biofuels Petter Hieronymus Heyerdahl

  2. GOAL: TO CONVERT WASTES AND DIFFICULT BIOMASS INTO BIOFUELS AND VALUABLE PRODUCTS Technology for 2nd Generation Biofuels

  3. Gases:CO, CO2, H2, CH4 Biomass is heated to 300 - 600 ºCin the absence of air ina gas thightreactionchamber. Biomass input Vola-tiles Condenser Microwaveenergyinput Liquids Char / Carbon and inert solid material Pyrolysis: Braking down (lysis) of a material by heat (pyro) Technology for 2nd Generation Biofuels

  4. H O H - + Microwaves are radio waves Technology for 2nd Generation Biofuels Radio waves travel through biomass Molecules are put into motion – that is heat Frequency: 2450 MHz Wavelength: 12 cm.

  5. Heating by microwaves Technology for 2nd Generation Biofuels

  6. CHARCOAL Main components of the microwave pyrolysis reactor 3 x 1.5 kW-generators To distillasjon or condensation Feedstock10 kg/h Technology for 2nd Generation Biofuels Quarts glass window Purge gas inlet 5 m Motor Ø 250 mm C + inert

  7. Properties of the continuous MWP plant: • Totally closed system • No air or oxygen added: – minimum gas volumes generated – high calorific value on gases • Low thermal masses of the reactor give short start and shut down times • Precise temperature control:- Low carry over of pollutants- Facilitates better product control • Small plants can be profitable • Electric input 5 – 25 % of feedstock energy content Technology for 2nd Generation Biofuels

  8. MWP of aspen Technology for 2nd Generation Biofuels

  9. MWP of municipal solid waste Technology for 2nd Generation Biofuels

  10. Why MWP? Conclusion • Powerful tool in concentration of hazardous components in biomass and waste streams • Waste reduction and in-process separation • Conversion of biomass and bio wastes for bio fuels, energy and bio chemicals • Attractive tool in education and international collaboration • Development of new technology – industrialisation Technology for 2nd Generation Biofuels
