dc.description.abstract | Bio-heavy oil (BHO), a mixture of remaining free fatty acids and glycerides is released as waste materials from biodiesel synthesis process. However, the complexity and impurities in BHO are drawbacks for its valorization due to essential requirement of multiple pretreatment processes. In this study, a direct valorization of BHO into value-added gaseous products was investigated using pyrolysis under CO2 condition. CO2 was used to achieve two goals: (1) establishment of environmentally benign platform using a greenhouse gas, and (2) carbon redistribution between CO2 and BHO to produce more value-added products. Pyrolysis under both CO2 and N-2 showed the conversion BHO into syngas and CH4. However, CO2-mediated pyrolysis had additional CO generation with decrease of the volatile matters from BHO pyrolysis. These resulted from gas phase reaction (GPR) of CO2 with volatile matters. To further activate the thermal cracking of BHO and GPRs, multi-stage pyrolysis and catalytic pyrolysis was performed with Co catalysts. CO2-mediated catalytic pyrolysis resulted in both significant formations of CO and H-2 from GPRs and dehydrogenation. Therefore, the proposed technical platform could be considered a viable environmentally benign way for waste valorization. | - |
