Abstract Scope |
Inorganic compounds inside or attached onto biomass feedstocks significantly affect the tool life in size reduction and pre-conversion processes. The conventional combustion-based ash extraction inevitably alters the inorganic compounds due to oxidation and thermal decomposition. Composition-preserving methods are presented here for extracting and analyzing both the extrinsic and intrinsic inorganic compounds. Comprehensive characterization has been conducted on different types of biomass. The extrinsic inorganic compounds are dominated by quartz along with other minor minerals, and the particle sizes are of a few hundreds of micrometers. Among the pine anatomical fractions, needle contains the highest intrinsic silicon content while bark trapped the most extrinsic minerals. By correlating to the wear, both the extrinsic and intrinsic inorganic compounds are believed to play important roles in the wear process. Results here validate a new approach to characterize the biomass inorganic compounds and provide fundamental insights for their impact on the preprocessing tool wear. |
