Crushed bark is gasified in a fluidized-bed gasifier operated with steam as the main gasification agent. The raw gas is at first filtered with innovative metal filters of GKN and then tars and light hydrocarbon gases are reformed using the staged reformer concept of VTT. After the reformer, syngas is cleaned from sulphur species and other remaining contaminants in the robust final gas cleaning train developed by VTT. Clean syngas is compressed and led to the Fischer-Tropsch reactor of INERATEC. FT-products are collected for further studies as two streams: the wax product and the FT-liquids.
The first one-week-long validation test run is now ongoing successfully and the first batches of bark-derived FT-products have been already collected. The whole process works as planned which is a great success for the COMSYN Project Team. This experimental campaign is realized as a collaborative effort of VTT and INERATEC.
