Mixed methanol/ethanol on transesterification of waste cooking oil using Mg/Al hydrotalcite catalyst

Biodiesel production from waste cooking oil using calcined Mg/Al HT (hydrotalcite) as heterogeneous catalyst was investigated. This study describes the calcined Mg/Al HT prepared under optimal conditions to catalyse waste cooking oil for biodiesel preparation and proposes a plausible catalysis mechanism. The catalysts were characterised by Fourier Transform-Infrared, X-ray diffraction, Thermal Gravity Analysis-Differential thermal gravity and …
