This deliverable is the second one in a series of deliverables describing the physico-chemical properties of fast pyrolysis bio-oil (FPBO) produced in the project. The first bio-oil batch (D2.2) was provided by BTG and the feedstock was pine. This pine bio-oil (R2H.BTG.2016.001b, as defined in D2.2) will be used as a reference during the project. VTT produced bio-oil from acid-washed forest residue and from pine. The second bio-oil batch from BTG arrived on 23rd August 2016 and included bio-oils from bark, Miscanthus, and sawdust. These results are included in D2.3 (M12) by BTG.
Numerous FPBO samples will be sent around between the partners over the course of the four-year Residue2Heat project. Sample delivery is a joint task, partners VTT and BTG will supply the consortium with conditioned FPBO samples. The sample delivery will be described throughout the project in seven deliverables (D2.2 – D2.8) and is connected to Task 2.1. To have a full overview, each deliverable report will be an updated version of the previous one, rather than a new report describing only the delivery in the relevant reporting period. A detailed analysis on the production of FPBO from different biomass and processing conditions will be documented in D2.1 (due in M26). Details on the analysis results of the various samples send to the project partners will be performed in T3.1 and its related deliverables (D3.1 – D3.8) which will provide feedback for WP2, and will be employed in WP4 and WP5 in modelling and utilization.
The deliverables D2.2 – D2.8 and D3.1 – D3.8 are primarily used for Residue2Heat internal documentation although they are marked as public. For the project partners it was essential to receive a documented fast pyrolysis bio-oil sample as soon as possible. The follow up deliverables will include more details and analysis concerning benchmarking of processes, comparison of data between VTT and BTG, the performance of measures to lower the water content (related to T2.1) and improve the phase stability.
