Emission of volatile organic compounds (VOC) from Drying and Storage of Biomass

Replacement of fossil fuels by biofuels has become increasing important due to both economic and environmental reasons. The emission of organic compounds of different green and dried biofuels that have been dried in hot air and steam medium, were analysed. Gas Chromatography (GC) with a flame ionization detector (FID) and GC mass spectrometry (GC-MS) have been used to identify the organic matter. The terpene content was significantly affected by the use of different biofuels, changing the drying medium. Comparison between spectra from dry and wet fuels reveal that the main compounds emitted during drying are monoterpenes- and sesquiterpenes-hydrocarbon, whilst the emissions of diterpenes-hydrocarbon seem to be negligible. The drying medium, which was either steam or hot air, is known to influence the distribution between different emitted terpene hydrocarbon matters. Hydrocarbon emissions from storing of biomass was compared during a storage period. The precipitation has an effect on the emission levels and on the pile temperature.
