2The diesel engine first patented in 1892
The Diesel engine was initially Intended to run
on coal dust.
Rudolph Diesel (1858 1913)
Diesel demonstrated his engine at the Exhibition
Fair in Paris, France in 1898. This engine was
fueled by peanut oil - the "original" biodiesel.
3The first Diesel race car placed 13th in the
Indianapolis 500
because it never stopped to refuel
4In 1973 and 1978, OPEC reduced the supply of oil
and raised the price.
The American public looked to diesel fuel which
was more efficient and economical and they began
buying diesel-powered automobiles.
This surge of diesel sales in American ended in
the 1980's.
5From the BBC
Just as certain as death and taxes is the
knowledge that we shall one day be forced to
learn to live without oil.
Only 1,000 billion barrels have been confirmed as
accessible to oil drilling. At current
consumption rates, the oil reserves will last
about 40 more years. With the rapid development
of both India and China, oil could be gone within
20 years.

7" The Use of vegetable oils for engine fuels may
seem insignificant today. But such oils may
become in course of time as important as
petroleum and the coal tar products of the
present time " Rudolph Diesel 1912

15HOW TO MAKE BIODIESEL
CONVERSION OF TRIGLYCERIDES TO METHYLATED FATTY
ACIDS
Four Key Ingredients
1. Vegetable Oil or Animal Fat (feedstock) 2.
Methanol 3. Catalyst (NaOH or KOH) 4. Heat
(or ultrasound for continuous flow processing)
The recipe (from NAFTC) National Alternative
Fuels Training Consortium 1 liter of oil
250 ml methanol (25 by vol.) 5 grams
catalyst (NaOH or KOH) React at 50-60 oC for
2 hours
In English Units 1 gallon of oil 1
quart methanol (25 by vol.) 0.7 ounces
catalyst (NaOH or KOH) React at 120-140 oF
for 2 hours
16HOW TO MAKE BIODIESEL
Calculations for KOH and methanol are based on
the amount of feedstock you are using
17HOW TO MAKE BIODIESEL
To begin
- Heat your oil to 50-60 oC (120-140 oF)
- Calculate the amount of methanol and catalyst
needed - Dissolve catalyst in methanol
- Add methoxide to heated oil
- Mix rapidly for 2 hours
18HOW TO MAKE BIODIESEL
Calculations for KOH and methanol are based on
the amount of feedstock you are using
Corn Oil 200 ml heated to 50oC

19After the reaction is complete. Turn off the heat
and mixing, and let settle overnight.
The glycerin will settle to the bottom of the
tank.

Glycerin
20Heating the oil can speed up the reaction by a
factor of 10. Be careful not to get too hot
Methanol boils at 65oC (150oF)
21DID YOU MAKE SOAP?
QUICK TEST TO DETERMINE IF YOUR REACTION WAS
SUCCESSFUL
22Soap and biodiesel are very similar compounds.
Biodiesel
Soap
Partial reaction (with soap)
23The catalyst (NaOH or KOH) is very hygroscopic
it will absorb moisture from the air
Initial mass
Mass increases after 5 minutes
24KOH is very hygroscopic it will absorb moisture
from the air very quickly.
This can promote soap formation.
Protect your catalyst from moisture using tightly
sealed containers. Or, consider storing under
dry nitrogen.

CONVERTING WASTE INTO FUEL
32HOW TO MAKE BIODIESEL
USED COOKING OIL REQUIRES TITRATION TO DETERMINE
AMOUNT OF CATALYST
High temperature cooking generates free-fatty
acids (FFAs) These will neutralize the catalyst
and disrupt the reaction
33BIODIESEL FROM USED COOKING OIL
USED COOKING OIL REQUIRES TITRATION TO CALCULATE
AMOUNT OF CATALYST
Mix 1 gram of catalyst (KOH or NaOH) in 1000 ml
distilled water
Mix 1 ml of used cooking oil in 10 ml of
isopropyl alcohol
34BIODIESEL FROM USED COOKING OIL
USED COOKING OIL REQUIRES TITRATION TO DETERMINE
AMOUNT OF CATALYST
Add measured quantity (1 ml or less) of 11000
catalyst solution (KOH or NaOH). Use the same
catalyst youll be using in your reaction.
If using Phenol indicator, the solution will
become pink when it becomes basic
If using pH paper, go until pH 8 is attained.
Record the amount of 11000 catalyst solution
used.
35BIODIESEL FROM USED COOKING OIL
Calculations for KOH and methanol are based on
the amount of feedstock you are using
For every 1 ml of the 11000 catalyst solution
added to the waste oil use an additional 1 gram
of catalyst per liter of oil feedstock
36BIODIESEL FROM USED COOKING OIL
Calculations for KOH and methanol are based on
the amount of feedstock you are using
Waste Oil 300 ml heated to 50oC
Methanol 75 ml
KOH 2.25 grams
Calculating the amount of methanol (same as
before)
300 ml Waste Oil x 25 methanol 75 ml
Methanol
Calculating the amount of KOH (must consider
titration results)
For Titration suppose you used 2.5 ml of
catalyst solution to raise the pH of the WVO to
8, then you would use an additional 2.5 grams of
catalyst per liter of oil in the biodiesel
reaction.

38Can you make biodiesel from cooked bacon fat?
39Solidified bacon grease
Biodiesel from waste bacon fat
40HOW TO MAKE BIODIESEL
Scaling up and water-washing to remove excess
glycerin
41Water-washing Removes excess glycerin
42Bubble wash or fine water mist to remove excess
catalyst and glycerin byproducts
43Poor quality fuel
44Magnasol avoids the water wash so you wont get
an emulsion.
But this doesnt mean youve made good fuel...
45Is this good fuel?
46The quality of fuel you need is dependent upon
your application
