VTT biofuel trial success leading to industrial scale-up

During September, the production of biofuel by gasification of biomass residues was successfully validated in the EU’s COMSYN project. The process performance was verified with crushed bark in an 80 hour-long test run at Finland’s Technical Research Centre – VTT. The syngas conversion to Fischer-Tropsch (FT) products was conducted by Berlin-based IneraTec.

The main focus of the test was to study and verify the performance of the gas cleaning train, and especially the entire synthesis process with real wood-derived gasification gas.

“The first validation test runs successfully demonstrated the efficiency of the compact gasification and synthesis process concept, as well as the production of FT-products, waxes and other hydrocarbons” said Principal Scientist Pekka Simell from VTT.

The crushed bark was gasified in a fluidised-bed gasifier with steam as the main gasification agent. The raw gasification gas was filtered with advanced metal filters supplied by GKN Sinter Metals Filters. Tars and light hydrocarbon gases were reformed using the staged reformer concept developed by VTT. Final cleaning of the reformed synthesis gas of sulphur and other remaining contaminants was realised through a robust sorbent-based cleaning process developed by VTT.

Based on the results, industrial-scale plants in the range of 25,000-50,000 tonnes per annum will be designed and techno-economic and environmental assessments, as well as business case studies, will be carried out by the DLR German Aerospace Center and two engineering companies: Wood from Italy and ÅF-Consult from Finland.

COMSYN is a four-year EU Horizon 2020 project that lasts from 2017 to 2021 with a budget of EUR 5.1 million from EU Horizon 2020. The project consortium consists of seven partners from four different countries combining research institutes, SME and top-level European industry. The project has received funding from the European Union’s Horizon 2020 research and innovation programme.

AcuComm’s WasteView projects database currently has 17 projects featuring the installation of Fischer-Tropsch technology, for further details search here.
