Co-production of high-quality silicon components, heat & power from ash-rich biomass via novel thermochemical conversion processes
The worldmarket for special silica(SiO2) productsand relatedderivativesis growingrapidly, especiallyconsideringtheir utilizationin devicesfor energyconversionand storage.
SiO2 synthesis is expensive, energy-intensive and environmentally harmful. It may therefore be justified to pursue and develop more sustainable production routes based on biogenic Si.
The aim of this research is to investigate the possibilities of developing thermochemical (combustion/gasification) processes to:
- extract Si components from the hot gases, which can be efficiently used in advanced material applications, e.g. in batteries and as raw material for solar cells
- avoid serious problems related to ash in the combustion/gasification process.
