Abstract
Increased environmental awareness and depletion of resources are driving to develop alternative
fuel from renewable resources that are environmentally more acceptable. Esters of fatty acids
(biodiesel, derived from the transesterification vegetable oils, have properties similar to components
of peh-oleior. based diesel fuel Cost has been a major factor slowing the commercialization of
biodiesel Glycerol is the coproduct of the esterification process. In this work the feasibility of the
glycerol of vegetable oil. with crude glycerol derived from the transesterification of the vegetable oils
and animal fats was studied. Utilization of the crude co-product of the biodiesel process was investigated
for improving the overall economy The transesterification of soybean oil for fuel purpose was
optimized. Optimization results are presented. transesterification of beef tallow produces a mixture
of esters which is more concentrated in the saturated fatty acids. Physical properties of these esters
are similar to esters of soybean oil. Reaction results and properties for beef tallow are presented.
