Choice of Suitable Additives and Design of Activation Procedure for Olivine
| 2017:400 | Pavleta Knutsson, Martin Seemann, Jelena Marinkovic
During biomass gasification biomass is transformed into product gas that
can be further used as fuel in the transport sector, for heat and electricity
production or as a resource for chemical synthesis. The gasification process
can be made more energy efficient if the procedure used for activation of the
bed material (olivine) in the gasifier is simplified.
The present study was performed in two units – the Chalmers gasifier and
the GoBiGas units. The effect of K2CO3, used as additive, was followed by
measuring the tar levels and monitoring the gas content of the product gas.
Bed material from both units was sampled under chosen conditions and
characterized by leaching and SEM-EDS and XRD.
The results show that addition of K2CO3 to the process can provoke immediate
response and improve the gas quality.
