  1. Energy and Fuels from Biomass and Waste Prof.dr.ir. Gerrit Brem Energy Technology Onderzoeksdag KIVI NIRIA, 19th of May 2011, Enschede

  2. Biomass Research at University of Twente • Faculty of Engineering • Faculty of Science • Faculty of Management and Governance Biomass is spearhead of UT!

  3. Energy Technology group • Faculty of Engineering • Since 2000 (2009) • 15 fte staff, PhD and post-docs • Academic and industrial network • Well-equipped laboratory

  4. Laboratory “Kleinhorst”

  5. Energy Technology group • Combustion of solid fuels “Energy from biomass and waste” • Production of sustainable fuels (liquid, gas and solid) “Fuels from biomass and waste”

  6. Combustion of solid fuels • Coal fired power plants “biomass co-firing” • Waste combustion

  7. Co-firing of biomass in power plants (combustion) Focus on: • Boilers with Ultra Supercritical steam conditions • High ratio of biomass co-firing • Slagging and fouling mechanisms • Development of modelling tools Sponsors: TSA, KEMA

  8. Co-firing of biomass in power plants (combustion)

  9. Co-firing of biomass in power plants (fouling)

  10. BioOxyfuel • Torrefied Biomass Combustion under Oxy-fuel Conditions in Coal Fired Power Plants • Combustion characteristics • Drop Tube Furnace Sponsors: STW, NVV, TSA, KEMA

  11. Waste combustion

  12. Ignition and combustion of waste on a grate • Ignition by flame radiation • Self-ignition • Mathematical modelling • Reversed combustion concept

  13. AVI pilot-plant

  14. Smart sensors for combustion and fouling Disturbances by fluctuating composition Waste Combustion plant Flue gas Boiler Smart Sensor Heating value + Fouling rate Steam temperatures Operator Gas concentrations

  15. Fuel production from Biomass • Flash pyrolysis • Gasification • Torrefaction

  16. Gas Biomass condenser PYROLYSIS REACTOR Char Separation Bio-oil Heat Char Flash pyrolysis of biomass

  17. Wood pyrolysis on lab scale - movie

  18. PyRos pilot-plant with 30 kg/h biomass feed

  19. Gas Biomass condenser PYROLYSIS REACTOR Char Separation Bio-oil Heat Char Near-future applications for pyrolysis oil

  20. Algae and scrap tyres • Oil from car tyres • Oil from algae

  21. 600 °C 300 bar high P gas/liquid separator C supercritical reactor low P gas/liquid separator feedstock Heat exchanger Gasification in supercritical water • Wet biomass • Process conditions: 600 °C and 300 bar • Production of a hydrogen or methane rich gas • Process integrated reactor • CO2 separation

  22. Torrefaction • Biomass is wet andbulky • Biomass sources are distributed • Pretreatmentrequired!

  23. Friableandlessfibrous • Hydrophobic • Preserved • Reducedcontaminations • Homogeneous • Higherheatingvalue Torrefaction process • On-site preparation of biomassbydrying, millingandtorrefaction (no external energy requirement) • Torrefaction: roasting of biomass at 250°C

  24. OCRI – Bioenergy with provincie Overijssel • Overijssels Centre for Research and Innovation • Grant of 2,5 Meuro • Cooperation with local industries • 9 postdocs (UT) • Research projects: > Catalytic pyrolysis for high-value fuels > Combustion of pyrolysis oil in gas turbines > Feedstock engineering
