1 0 Energy and Fuels from Biomass and Waste Prof.dr.ir. Gerrit Brem Energy Technology Onderzoeksdag KIVI NIRIA, 19th of May 2011, Enschede

2 1 Biomass Research at University of Twente  Faculty of Engineering  Faculty of Science  Faculty of Management and Governance Biomass is spearhead of UT!

3 2 Energy Technology group  Faculty of Engineering  Since 2000 (2009)  15 fte staff, PhD and post-docs  Academic and industrial network  Well-equipped laboratory

4 3 Laboratory “Kleinhorst”

5 4 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 5 Combustion of solid fuels  Coal fired power plants “biomass co-firing”  Waste combustion

7 6 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 7 Co-firing of biomass in power plants (combustion)

9 8 Co-firing of biomass in power plants (fouling)

10 9 BioOxyfuel  Torrefied Biomass Combustion under Oxy-fuel Conditions in Coal Fired Power Plants  Combustion characteristics  Drop Tube Furnace Sponsors: STW, NVV, TSA, KEMA

11 10 Waste combustion

12 11 Ignition and combustion of waste on a grate Ignition by flame radiation Self-ignition Mathematical modelling Reversed combustion concept

13 12 AVI pilot-plant

14 13 Combustion plant Operator Waste Disturbances by fluctuating composition Smart Sensor Heating value + Fouling rate Smart sensors for combustion and fouling Flue gas Boiler Steam temperatures Gas concentrations

15 14 Fuel production from Biomass  Flash pyrolysis  Gasification  Torrefaction

16 15 PYROLYSIS REACTOR Biomass Heat condenser Char Separation Gas Bio-oil Char Flash pyrolysis of biomass

17 Wood pyrolysis on lab scale - movie

18 17 PyRos pilot-plant with 30 kg/h biomass feed

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

20 19 Algae and scrap tyres  Oil from car tyres  Oil from algae

21 20 Gasification in supercritical water  Wet biomass  Process conditions: 600 °C and 300 bar  Production of a hydrogen or methane rich gas  Process integrated reactor  CO 2 separation C Heat exchanger supercritical reactor high P gas/liquid separator feedstock 600 °C 300 bar low P gas/liquid separator

22 Torrefaction  Biomass is wet and bulky  Biomass sources are distributed  Pretreatment required!

23 Torrefaction process  On-site preparation of biomass by drying, milling and torrefaction (no external energy requirement)  Torrefaction: roasting of biomass at 250°C Friable and less fibrous Hydrophobic Preserved Reduced contaminations Homogeneous Higher heating value

24 23 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
