Analysis of the effect of temperature on the morphology of egg shell calcium oxide catalyst: Catalyst production for biodiesel preparation

Abstract

The increasing number of studies on the usage of egg-shell-derived Calcium Oxide (CaO) as a catalyst for biodiesel production highlights the need to investigate the effects of temperature on the calcination of egg shells. To this end, the present study investigates the calcination of chicken and duck egg shells exposed to different temperatures of 800°C, 900°C, and 1000°C for one hour. The synthesized CaO was characterized by X-Ray Diffraction (XRD), Fourier-Transform Infrared spectrometry (FT-IR), Scanning Electron Microscope (SEM), and Energy Dispersive X-ray analysis (EDX). This study showed that there were changes in the distribution and formation of calcium, oxides, and the naturally occurring substance carbon during calcination of the samples. It was observed in both chicken and duck egg shells that 800°C was a decent temperature for calcinating egg shells to produce calcium oxide catalyst.
