There
are two specific environmental diesel
products, RME (rape-methyl-ester), BIOL
and LME Line-methyl-ester), BIOLIN.
The raw materials are of cause vegetable oils for these esters and have a
specific molecule structure and therefore easy to produce with the "Cold
Process".
The
"Cold Process" works also excellent with other vegetable oils like cress,
olive, palm, soy, sunflower, etc. All these bio diesel products have the same
name: BIOL.
The "Cold Process" does not give birth to
soapy soup because
the process temperature is too low, less the +45 C.
Beyond
these two ordinary ones, you will find two special products produced from cooking
oil or animal fat including fish fat/oil.
Cooking
oil (recycled frying fat) holds a loot of different fats, oils and
other contaminations so the "Cold Process" has to be changed a little
to meet this problems. Even if the cooking oil holds more or less water, the
"Cold Process" worked properly with some small corrections.
A common name for this environmental diesel fuel is ESTROL.
FAME
as ESTROL and BIOL
can meet the SS-EN 14214 norm.
BIOIL
and ( BIOLIN)
meet the DIN-norm, but have other
qualities.
In
the laboratory we developed the product with the "Cold Process" in the
end of the year 1988 and the raw material
was reused cooking oil .
It
is hard to make a technical report for this product because of the different
types of oils and fats. As an example we can mention that the density of the
cooking oil may range from 0,89 to 0,96 kg/l.
In
the year
2002 we repeated the trans estrification of used cooking oil with good result. The
used cooking oil from one restaurant proved to contain up to 3% water and
another restaurant proved to contain additives of different acids. These two
problems make it a little tricky to use the "Cold Process". Therefor it is good to
have a high quality control before the trans estrification.
This
Product is a part of the "Cold Process" and suitable for cleaning
asphalt, chewing gum, tar etc.
Excellent
for cleaning oil tanks, outdoors as well as indoors.
BIOIL
is biological resolved within 21 days, as well as RME.
An environmental and renewable diesel fuel was developed in 1983 - 1985.
Three important criteria were to be put up and realized for the process:
1. Simple to handle.
2. Normal air pressure.
3. Normal indoor temperature.
1.
The meaning was that farmer could earn
a little if he/she use this
process.
To sow, harvest, press and trans estrificate his/hers own rape/line oil was the hint. It was possible to reuse the milk tank, milking machine and other equipments on the farm to build a process room.
2. The process pressure must be normal air pressure*
3. and also the temperature must be normal indoor temperature*.
* Both for security reason.
Consequently the method is
called:
