Abstract

Hydrotalcite is anion compound capable of exchanging ions; it has the potential as a catalyst and adsorbent for variety of applications. Hydrotalcite can be prepared through several approaches, depending on the specific need and the characteristics of the compound. In this study, hydrotalcite was prepared through combustion method using glycine as fuel for the first time. Glycine was selected as opposed to urea so that hydrotalcite is safe for use in food processing or health. Hydrotalcite that was successfully obtained via combustion technique using glycine as fuel showed interesting characteristics. The compound demonstrated high thermal endurance and highest alkalinity, which suited the application for biodiesel production from vegetable oil and hydrogenation in the making of fats. However, the surface area was low in comparison with the same compound obtained from co-precipitation and sol-gel techniques.

 

Keywords: hydrotalcite, catalyst, sol gel technique, combustion method, co-precipitation method, bio-diesel
