Tóm tắt

Solvothermal liquefaction (STL) can convert kitchen waste (KW) into bio-oil without pre-drying. This study systematically investigated the effects of Fe-Ni bimetallic catalysts and recycled ethanol on enhancing bio-oil production. It also assessed the stability and reusability of the recycled catalysts, as well as the environmental benefits of STL technology. Compared to non-catalytic liquefaction, the Fe-Ni bimetallic catalysts significantly promoted the hydrodeoxygenation and esterification processes in bio-oil production. The highest yields of hydrocarbons (13.52%) and esters (69.86%) in bio-oil were achieved using the 6Fe-10Ni/Al
