dc.description.abstract | As the consumption of plastic materials has been dramatically increased, the abundant presence of their debris has become a significant problem worldwide. Thus, this study proposes a sustainable plastic conversion platform for energy recovery. In detail, polystyrene pyrolysis was examined as a case study under CO2 atmosphere in reference to N-2 condition. The major gaseous and liquid products from polystyrene pyrolysis include permanent gases (syngas and C1-2 hydrocarbons) and condensable aromatic compounds. Under CO2 environment, the reduction of polycyclic aromatic hydrocarbons (PAHs) was achieved during polystyrene pyrolysis, in comparison with N-2 condition. Since its slow reaction kinetics, conversion of condensable hydrocarbons into permanent gases was not fully activated. Therefore, a cheap industrial waste, steel slag (SS), was employed as a catalyst to increase reaction kinetics. The synergistic effects of SS and CO2 contributed to doubling H-2 production, while CO formation increased more than 300 times, in reference to non-catalytic pyrolysis. Because CO2 acted as an oxidant for CO production, control of H-2/CO ratio was achieved in different conditions. Thus, the utilization of CO2 would suggest a promising way to reduce the formation of PAHs, adopting the reliable platform to produce syngas from plastic waste. | - |
