Brief description
The project serves the further development and optimization of the process of catalytic partial oxidation of fuel gas containing tar, which was already examined and proven at the Dresden University of Technology.
The objective of the project is to eliminate the disadvantages and inadequacies of the catalytic partial oxidation process, that have occurred during the previous investigations.
This means in real terms that the long-term stability of the catalyst has to be improved and a reduction of the dilution effect by avoidance of nitrogen has to be achieved.
On the basis of experiences, a suitable combination of a catalyst and an oxygen carrier is being sought in the framework of the project in order to make a motor use of biogas from wood gasifiers possible. The construction, structure and material of the catalyst in variation shall be specifically investigated.
Test rigs used / special purchases
The suitability of the concept that shall be newly developed will be demonstrated at the test facility for gasification at the Dresden University of Technology under real circumstances of biomass gasification. A reactor for testing will be designed and built by the Haase energy engineering company.
