2 Objective of BERG To apply chemical engineering science and technology to help provide sufficient energy, fuels and chemicals from renewable and sustainable resources for the needs of today and tomorrow.

3 Achievements International leader in thermal biomass conversion research Funding of more than £22 million Operational since 1979 Collaborators in 33 countries Partners in 14 countries * *

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

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
