Production of biodiesel from waste frying oil using waste calcareous-onyx as unique esterification and transesterification catalytic source
Biodiesel was produced from waste frying oil (WFO) using waste calcareous-onyx as catalyst. The free fatty acids (FFAs) present in WFO were first esterified with methanol using calcareous-onyx powder calcined at 700 °C (Onyx-700), and the triglycerides transesterification was catalyzed by waste calc...
