Menetelmä ja laite pyrolyysinesteen laadun parantamiseksi

摘要

Water and low molecular weight reactive chemicals compounds are removed from the pyrolysis vapours and/or liquid by evaporation and/or preventing complete vapour condensation. A process for the preparation of liquids by pyrolysis, comprises the rapid pyrolysis of biomass and/or similar organic material in order to vaporise volatile compounds, and the condensing of these vapours to form a liquid. Water and low molecular weight reactive chemical compounds are removed from the pyrolysis vapours and/or liquid by evaporation and/or preventing complete vapour condensation, in order to improve pyrolysis liquid quality. An Independent claim is also included for the process apparatus, comprising a pyrolyser (1), condenser (2) and at least one device (10, 11) for removing water and low molecular weight reactive chemical compounds.
