Characterization of pyrolytic products obtained from fast pyrolysis of chromated copper arsenate (CCA)- and alkaline copper quaternary compounds (ACQ)-treated wood biomasses

► CCA and ACQ treated waste wood were pyrolyzed at 500 °C for ca. 2 s. ► Major pyrolytic products - biooil, char and gas - were obtained from CCA-W and ACQ-W. ► Arsenic was distributed equally to the three pyrolytic products. ► Copper and chromium were mainly retained in the char.
