Comparative Esterification of Agricultural Oils for Biodiesel Blending

摘要

A well established batch procedure was used to develop technical and economic data for the production of biodiesel from chicken fat fractions, as well as various grades of refined and unrefined rice bran and soybean oils. Material balance calculations showed that the yield of biodiesel increases with increasing quality of oil/fat. Refined, bleached soybean oil, degummed soybean oil, refined, bleached rice bran oil and high yield chicken fat produced the most biodiesel, yielding an average of 0.88 ml of biodiesel per ml of oil/fat. All of the samples tested met the standards for cetane number, heat of combustion, cloud point and copper corrosion, while only some of the samples met the standards for kinematic viscosity, flash point and sulfated ash.
