Abstract

Solid heterogeneous based catalysts are one of major materials for the transesterification and pyrolysis of edible or non edible oils because they are normally more reactive than solid acid based catalysts which require severe operating parameters. Calcium oxide based nanocatalyst has shown improved catalytic activity because of its high basicity as required during the transesterification reaction process of triacylglycerides (TAGs) and in pyrolysis process. In the present study, waste chicken egg shell based nanocatalyst derived from calcium oxides as a heterogeneous catalyst was synthesized and characterized using Fourier transformed infrared spectroscopy (FTIR) and X-ray based diffraction (XRD). The FTIR as well as XRD results have clearly shown the synthesis of heterogeneous based calcium oxide nanocatalyst from waste eggshell, which is normally composed of calcium carbonate. Therefore, waste eggshells can be considered as the promising technique and resource of calcium for the applications in various fields.
