The SmartCHP project has produced a new study investigating “The production of fast pyrolysis bio-oil (FPBO) from selected feedstock”. The study has been performed by BTG Biomass Technology Group BV (The Netherlands) as part of the project and its research on biomass and FBPO production.
Fast Pyrolysis Bio Oil (FPBO) can be produced from a variety of lignocellulosic biomass materials. In this report the results are presented concerning the production of FPBO from the biomass feedstocks selected in the SmartCHP project. The FPBOs are used within the project for further development work of the SmartCHP system. Important properties such as heating value and moisture content are included in this report as well to derive mass, energy and carbon balances and ensure this report can be read without consulting the other three related reports which are confidential. The biomass selection is based on availability, suitability and sustainability. Five scenarios are made covering four different biomass materials and one import scenario:
- Agricultural residues – corn stover – Romania
- Organic waste – olive kernel – Greece
- Woody biomass – forest residue – Sweden
- FPBO import scenario – Sweden to the Netherlands
- Dedicated bioenergy crop – miscanthus – Croatia
Three biomass materials were selected and supplied by Capax Biobased Development (Belgium) for conversion to FPBO in BTGs bench-scale pyrolysis plant (see the scheme below). For the fourth material (miscanthus) previous tests have been performed at BTG and sufficient information is already available as input for the scenario studies. FPBO produced from miscanthus is also available for testing. The results from the experimental work showed that each of the materials could be processed in the bench-scale pyrolysis plant without operational problems. The FPBO production results show that the wood residues generate the highest FPBO yield (68 wt.%) followed by corn stover (56% wt.%) and olive kernels (49 wt.%). The FPBO derived from wood residues was a single-phase homogeneous liquid. Both corn stover and olive kernel derived FPBO consisted of an aqueous phase and an organic phase which needed to be conditioned (partial water removal) to generate a homogeneous liquid.
