Two Stage Method
Chicken fat oil
Acid Esterification (Methanol +H2SO4 )
At 65 °C
for 50 min
At 68 °C
for 50 min
Base Transesterification (Methanol+ NaOH)
Glycerin settling and separation
Temp above 70 °C
Washing (4-5 times)
At 110 °C
FAME/ Dry Bio-ethanol
Glycerin used to produce three forms of energy:
IUPAC Name: Propane-1,2,3,-triol
Molecular formula: C3H8O3
Yield: 100 ml of glycerin from 1000ml of the chicken fat through trans-esterification process.
Colour: Dark Brown
Texture: Semi-solid, thick syrup-like consistency
Molecular Weight: 92.09
Density: 1.22 – 1.24 g/ml at 25°C
Viscosity at 40° C: 8.68 centistokes
Flash Point: 120°C
Melting Point: 18°C
Boiling point: 130°C
Freezing Point: 2°C
Fumes on addition of Sulphuric acid
% Ash = (Weight of ash * 100) / weight of sample = 1.88 %
% Moisture Content = 3.0345 %
Vaccum distillation unit
% yield = (Yield/ Wt of sample)*100

Emission test : The samples were burnt and tested for emissions in a gas analyzer by inserting the probe.
The CV is measured by burning it in a controlled environment. The resulting heat released by this combustion i.e. the net temperature rise, is proportional to the calorific value and was tested by firing the coal in Bomb calorimeter at Bangalore Test House.
The gly-coal burning capacity was tested by boiling water using 50 grams of gly-coal and parameters such as time and temperature were recorded.
Fermentation using Yeast
150 ml of ethanol was produced.
Ethanol after titration
On adding starch
Concentration of ethanol obtained= 21 %
The effects of glycerin on the performance of anaerobic digester were examined by adding glycerin in order to enhance methane production.
The supplementation of the feed with crude glycerol had a significant positive effect in methane production rate.
Feeding with glycerin
Rising of the Gas holder tank
Characterization of Gly-gas
All by-products of biodiesel production provide valuable feedstocks for power generation. The results can be summarized in few points:
Overall, crude glycerin has various applications and we have experimented with a few of them.
The results were mainly 3 important sources from a process industry waste .
