2. TABLE OF CONTENT
• Introduction
• Different types of Feed Stock & oil
Characterization
• Property of feed stock
• Esterification and transesterification
• Post Treatment Processes
• Different types of heterogenous catalyst
preparation
• Biodiesel Characterization as per ASTM
3. INTRODUCTION
• Biodiesel is a renewable,
biodegradable fuel that is a cleaner-
burning alternative to petroleum-
based diesel fuel.
• It is produced from renewable sources
like vegetable oils, animal fats, and
waste cooking oil.
• BIODIESEL YIELD CALCULATION :
Net biodiesel weight x % FAME GC
given oil weight
5. PROPERTIES OF Feedstock
• FORMULA:
• FFA(FREE FATTY ACID) = ACID VALUE X (0.5 to 0.75)
• We are considering only 0.5
• FFA ( FREE FATTY ACID ) : For castor Oil FFA is 3.5
• So Acid Value will be 1.75 mg KOH/gram of oil
Acid Value should be less than 2%.
6. • Transesterification is the catalyzed reaction of oil or fat
with alcohol to yield an ester and glycerol
ESTERIFICATION :
• Esterification is the process of combining an organic acid
(RCOOH) with an alcohol (ROH) to form an ester (RCOOR) and
water.
TYPES OF REACTION
TRANS - ESTERIFICATION :
7. Alcoholic Solvent
(Methanol , Ethanol , Propanol etc. can be used) but
we used methanol for the economic purpose
• SOLVENTS :
SOLVENT & CATALYST USED
• CATALYST :
• For Esterification we used H2SO4 as a Catalyst and the
catalyst loading is 1.5 %
• For Transesterification we used KOH as a Catalyst with the
catalyst loading of 1 %
8. • CONVENTIONAL METHOD : Taking a Batch of 50g castor oil and
mixture of 17.1 g Methanol and g H2SO4 is prepared. Molar Ratio 1:10

• CONVENTIONAL METHOD :
SYNTHESIS OF BIODIESEL
Washing with Di-Water Removing Moisture by Magnetic Stirrer
Then collect it in different
Glassware
We didn’t get Biodiesel from this
because there is less presence of
FFA in the oil and also this
technique is less effective
10. SYNTHESIS OF BIODIESEL (TRANSESTERIFICATION)
High Speed Grinder
ROTARY FLASH EVAPORATOR FOR
METHANOL RECOVERY
SEPARATING THE MIXTURE
From high Speed Grinder : Taking a Batch of 255g Karanja oil and mixture of 52g Methanol and
2.5 g KOH is prepared. Molar Ratio is 1:6.
11. HETEROGENEOUS CATALYST SYNTHESIS
Cao (Calcium Oxide) From Egg Shell
Fe3O4(Ferrous Oxide) From FeCl2 And FeCl3
Srx/Fe3-xO4 From Strontium Nitrate
By Co-Precipitation Method
Preparation of SRx 2gm Fe3O4 Mixed With 30 ml Di- Water, Putting it in Magnetic Stirred
for 20 Minutes, then Add Solution of Strontium Nitrate of 0.731 gm in 20 ml dropwise,
Maintain Temperature at 90 Celcius, then we added Ammonium Hydroxide for
Precipitation And Kept for 2 Hours.
