Abstract

In this work, conversion of various tar representatives over the surface of heavy metal contaminated biochars was investigated. To determine the effect of biochar porosity on its interactions with the tar, a portion of biochar was submitted to activation via gasification using CO2 and CO2/steam mixtures. Conversion of three model tars was analysed. Additionally, experiments with real tars generated by pyrolysis of wood chips and individual wood components were performed.
