Biodiesel Production from Castor Oil in the Liquid Phase using Acidic Alumina as a Catalyst
J. Environ. Nanotechnol., Volume 8, No 1 (2019) pp. 38-41
Abstract
Biodiesel is technically defined as alkyl esters of long-chain fatty acids, derived from vegetable oils or animal fats. It is an eco-friendly fuel, compared to petroleum-based hydrocarbons. This renewable and biodegradable advantage makes biodiesel a good sustainable energy carrier. It is usually produced by a trans-esterification reaction of vegetable or waste oil with low molecular weight alcohol, such as ethanol and methanol. In this work, ethanol has been used for the production of biodiesel, by using castor oil as a source material and acidic alumina as a catalyst. Experimental conditions like time, temperature, molar ratio and catalyst dosage were optimized to obtain maximum conversion. The product obtained has been characterized by FT-IR and NMR techniques.
