Description

The aim of the research presented the removal of halogen compound on pyrolysis oil from e-waste adsorptive pyrolysis. Fly ash from coal-fired (LNFA) and rice-husk-fired (RHFA) power plants were considered an al-ternative adsorbent. Adsorptive pyrolysis was performed in term lab scale and pilot scale. Condition of pilot scale was optimized by lab scale-pyrolysis experiment. LNFA performed well for debromination, with a 51.4% decrease of Br in pyrolysis oil compared to thermal py-rolysis. RHFA performed well for debromination and dechlorination, with a 36.6% Br decrease and 47.6% Cl decrease in pyrolysis oils com-pared to thermal pyrolysis. LNFA performed debromination ability in PCB oil while RHFA was preferred for dehalogenation during PCB oil and WC oil.
