dc.description.abstract | To valorize tea waste (TW), catalytic pyrolysis was done as a practical measure for recovering energy as a form of syngas. Considering CO2 as a reactive gas medium in place of conventional pyrolysis gas, a sustainable pyrolysis platform was established. In addition, mechanistic effectiveness of CO2 on TW pyrolysis was examined. In the presence of CO2 , homogeneous reaction with volatile organic compounds (VOCs) derived from TW pyrolysis contributed to CO formation. To enhance the formation of syngas at low pyrolysis temperature, catalytic pyrolysis over a Ni/SiO2 was investigated. The synergistic effects of Ni/SiO2 catalyst and CO2 promoted thermal cracking of VOCs and further homogeneous reaction with CO2 , thereby resulting in the substantial enhancement (28 times more) of H-2 and CO production than non-catalytic pyrolysis. It was also confirmed that CO2 could be considered a reactive gas medium to produce biochar (34-35 wt.% yield), having competitive porosity and surface area, in comparison to that from pyrolysis in N-2. Therefore, CO2 can be employed to build a sustainable waste conversion platform for energy and biochar production through pyrolysis instead of using N-2. | - |
