Abstract:
... In the present study, the possibility of extracting biogenic silica from various European biomass materials was investigated. High-purity biogenic silica (>90 wt % SiO₂) was obtained from energy crops (miscanthus), agro wastes (wheat straw), and other crop residues (cereal remnant pellets). Three different morphological forms of biogenic silica materials (ash) were obtained by a thermo-chemical tr ...
