BERGscope and activities Wood, Energy crops, Residues, Wastes Biomass production & processing Prepare and pretreat Biological conversion Hydrolyse Ferment Thermal conversion Pyrolyse Gasify Processing Upgrade Refine Synthesis Refine Biorefinery Products & Markets Chemicals Biofuels Electricity, Heat System Integrated bioenergy system

  5. Focus • The main focus of our research is fast pyrolysis • This is an advanced thermal process that produces up to 75% wt. liquid (bio-oil) from biomass with some byproduct char and gas • The liquid can be used for: • Power generation in engines and turbines • Heat in boilers and co-firing • Chemicals directly or via upgrading and separation • Energy carrier to reduce handling & storage of biomass • Biofuels by upgrading

  6. 5-7 kg/h fast pyrolysis fluid bed Continuous bubbling fluid bed with full computer control Liquid collection by quench and ESP Gas recycle for fluidisation

  7. 1 kg/h fast pyrolysis fluid bed

  8. 100 and 300 g/h fluid bed • 4 continuous fluid beds : 100 g/h to 5-7 kg/h • 2 continuous ablative reactors : 4kg/h and ~20kg/h, • Hot vapour filter • Microwave micro-reactor, • Synthesis micro-reactor • TGA and Py-GC-MS/FID

  9. 20 kg/h ablative pyrolysis reactor Heat • Biomass in Heat Heat • Char out Heat • Vapoursout

  10. Bio-oil blends with bio-diesel • Results • Three phase chart for blends with bio-butanol • Initial Newtonian behaviour • Long term stability pending

  11. Other facilities Micro-reactors • CDS high pressure and catalystreactor system • Microwave • Pressurised synthesis and upgrading reactor • Autoclave Analysis and characterisation • Extensive facilities for analysis and characterisation of: • feedstocks • intermediates • products

  12. Our contributions to fast pyrolysis • Biomass pretreatment and preparation • Fast pyrolysis in fluid beds (4 units) and ablative (2 units) • Reactor design and modelling • Analytical pyrolysis • Catalytic pyrolysis • Liquid collection and upgrading • Extensive liquid analysis and characterisation facilities • Chemicals recovery and refining • Nitrogenolysis for fertiliserproduction • Biofuel production by Fischer-Tropsch synthesis, zeolites and hydrotreating upgrading of fast pyrolysis products • Technical and economic assessment of bioenergy chains for electricity, biofuels, chemicals, biorefineries

  13. Bioenergy chain Power Heat Biofuels Chemicals Power & heat generation Thermal conversion Combustion, Gasification, Pyrolysis Biomass Preparation & Pretreatment Products Biofuelchain Biofuel production & refining Chemicals production

  18. Process modelling • Processes are being modelled in terms of: • Performance • Capital cost; Product cost • Environment; Socio-economics • Variability is considered in terms of: • Scale • Uncertainty; Learning • Process design; System design • Objectives include: • Impact of pyrolysis as pretreatment method • Process route to hydrocarbons • Integration with refineries • Fertiliser production as Ammonia and Slow release fertiliser

  19. Process model – 3252 processes

  20. European Bioenergy Research Institute • BERG is a founder member of EBRI – the European Bioenergy Research Institute • EBRI will create a unique platform for the development and implementation of bioenergy systems in local, national and European contexts as well as reaching for International community
