COMSYN Project - Compact gasification and synthesis process for transport fuels


Winter 2020

COMSYN project develops a new BTL production concept by means of a compact gasification and synthesis process.

Biofuel production costs will be reduced by up to 35% compared to alternative routes. This means less than 0,80 €/l production cost for diesel. The production concept is based on distributed primary conversion of various kinds of biomass residues to intermediate liquid products with small-tomedium scale units located close to biomass resources.

The primary conversion will be integrated to local heat and power production resulting in 80% energy efficiency in biomass utilization. The FT products will be refined to high quality drop-in liquid transport fuels at existing oil refi neries, bringing the benefi ts of economy of scale to the overall process. In addition, the novel gasifi cation technology will enable the use of wider feedstock basis.

Biomass residues to Fischer-Tropsch products
In COMSYN project, the production of biofuel by gasification of biomass residues was successfully validated in two 80 hours tests campaigns in 2019. The focus was to study and verify the performance of the gas cleaning train, and especially the entire synthesis process, with real wood-derived gasification gas. Crushed bark was gasifi ed in a fluidized-bed gasifier, the raw gasification gas was filtered with advanced metal filters of GKN. Tars, and light hydrocarbon gases were reformed using the staged reformer concept developed by VTT. Final cleaning of the reformed synthesis gas was realized through a robust sorbent-based cleaning process developed by VTT. The ultra-clean syngas was compressed and led to mobile synthesis unit, MOBSU, which utilizes the innovative compact FT-technology of INERATEC. Two products, the FT- wax and FT-oil streams, were collected (Fig.1) and refined to high-quality transport fuels by UniCRE, assisted by VTT. Based on the achieved results, industrial-scale plants in the range of 25000–50000 tn/a will be designed. Techno-economic and environmental assessments and business case studies will be also carried out.


COMSYN is a 4-year (2017-2021) EU Horizon 2020 project under grant agreement No 727476.
The project consortium: VTT, coordinator (Finland), DLR (Germany), UniCRE (Czech Republic), INERATEC (Germany), Wood (Italy), GKN Sinter Metals Filters GmbH (Germany) and AFRY (Finland).

Latest results of COMSYN & FLEXCHX projects will be presented at Webinar "Compact Gasification and Synthesis for Flexible Production of Transport Fuels and Heat" on 19 January 2021, 10:00-12:20 CET. Registration is open at:
