We will obviously not be able to count on the government to help us clean up the planet by making our fuel ... All the more reason to gather information to make the process available to all individuals.

Unfortunately, the process is kept secret ...

Thank you Cuicui for the links,

Regarding the US and their revolutionary process, it may be as disappointing as the communication is pompous.

It is biomass thermolysis, I want to believe a little optimized, but it's not new ...

And so we must burn some of the biomass to thermolysing the recycled part in gasoline, or Diesel, via Fischer Tropsch reactions ...

yes it exists since 1920 but it is very promising!

the manufacture of biogas can be generated from waste, innumerable to date given the industrial society that does not eliminate them enough. (waste of maize, milk, sewage sludge, forest, pork slurry, cows etc ...)

good, of this gas it can be used locally already, in networks of heat.

in France, 4 biogas production instalaltions, in Germany 3500, in sweden a train runs on biogas ...

then the fischer-tropps process works very well and arrives at a fuel, the sunfuel or sundiesel, of 0.6 € the liter.

it is to be thought that the pork-fed Makhonin used during the war, or gasifier, is a system for transforming wood gas or coal into fuel!

this process was fassait from wood using a simple oven!
makhonine died in France in 1973, at the time of the 1er oil shock ...

thank you cuicui for these links.

What has become of Dr. Laigret?
We will not dwell on the reasons which led to an incredible oblivion of his major and historical discovery. But it is clear that it could hardly, in 1950, serve as politico-financial interests ... What about our very problematic time? Man of talent and truth, little concerned about his personal careerHe was no less known for his work on tropical diseases when he began to study methane fermentation. He had directed important works and he was correspondent of the Institute at the time of his death in 1966, there is now 40 years ".


.. still a scientist researcher thrown in the trash who did not want to make a career. Today these people are even more despised than 1950 ..

thank you jonule for the links:

The sundiesel, that benefits:

Biotrol / SunFuel / SunDiesel
The name of Sunfuel was imagined by Volkswagen. Mercedes-Benz uses the name Biotrol. Meanwhile the two companies seem to have agreed on the name of SunDiesel. Its producer is the German company Choren Industries.

SunDiesel® is a transparent and oily liquid, containing no sulfur or aromatic compounds. It contains significantly fewer harmful substances than a fossil fuel (from 35 to 55% less) and its combustion itself produces less. BtL differs mainly from diesel by its purity. Diesel contains the order of 400 substances. The Sundiesel contains only about ten.

A more precise specification - either the engine or the biofuel - allows cleaner combustion. An additional advantage is the high cetane number, greater than 70 (the minimum level for the EU is 49)


We talk about it here :

Must talk to angry fishermen :D

Does it work with freshly cut grass? : I put some in my compost silos and the rest in heaps next because I have a significant surface + that of my stepfather ..... and it grows when it rains like lately.

If I understood correctly, Jean Laigret used the action of bacteria to turn waste into liquid fuel. So no need for high temperatures. If this is confirmed, we could imagine small inexpensive installations to turn the contents of our garbage cans into diesel ...

uh, RemundoDid you read the article? : Shock: http://www.lagrandeepoque.com/LGE/content/view/879
Dr. Laigret then decided to pursue his research starting from solid bodies and first a fatty acid: oleic acid.The product used was ordinary commercial soap, made with olive oil. His work was conducted under the same conditions as before and with the same bacillus.He found that the fermentation did not produce methane but carbon dioxide and that it deposited on the surface of the fermented medium a black liquid whose analysis showed It was an oil, and more precisely, one hundred grams of soap gave 75 cm3 of oil.The experiment was repeated several times with the same result.
This confirmed the fact that until now it had merely been assumed that oil deposits came almost certainly from the anaerobic fermentation of organic matter and the process that had allowed it could be reproduced in the laboratory. This did not mean, of course, that other types of fermentation or bacilli did not lead to the result, but it was now certain that the bacillus perfringens caused the synthesis of oil.
The yields of "oil" have proved remarkably high from the outset: one hundred grams of oleic soap giving ¾ of their mass in oil!
"Vegetable oils have the best oil yield during fermentation. On average, one ton of fermented oil gives 800 liters of crude oil and 200 m3 of combustible gas. But oils are relatively expensive products and the collection of plants that contain them is an artisanal operation, so expensive. Hence Dr. Laigret's idea of ​​studying the fermentation of cheap organic products.
Thus he found that kitchen meat waste could provide 450 liters of oil and 140 m3 of combustible gases per ton. The fish waste provided about 70% of their weight of carbides. The barks of oranges and lemons 37% and the dead leaves 25% of their weight ... »
A plethoric source of organic matter very cumbersome and whose valuation is infinitely desirable is obviously constituted by sewage sludge, especially those corresponding to large urban concentrations.
It is known that today a portion, brought to a dry matter content of about 50% is burned, while the rest is converted into a cheap agricultural fertilizer, sold at low prices and whose use does not. is not without drawbacks ...
Could be added to the sewage sludge and directed in concert to appropriate fermentation tanks various organic waste, garbage, "pile fund" oil mills, slaughterhouse waste -whose blood is not really known what to do Even nowadays, "meat-meal", a modern calamity ... but also the carcasses of "crazy" cows or aphthous sheep ... or the corpses of "avian" chickens, as well as the marine algae of interest as a material organic fermentable, and further containing traces of iodine whose presence promotes the fermentation process.
It is probable that the cost price of finished products comparable to the current petroleum products would not be of a very different order from that which was set at times of relative serenity ... that is to say before 1973, and even before August 1990. on the other hand, it is necessary to consider the immense economic advantage that would be the containment of the outflows of currencies consecutive to the purchases of crude.
The process studied by Dr. Laigret is intended to replace more or less long term fuels used by our engines. Now, it is possible to estimate at some 30 millions of tons the quantity of oil necessary. Note that this is the only energy 'on board', that is to say the one we use annually for the propulsion of vehicles.
These are data from the IFP and corresponding to the average annual French consumption of the 1990 years, which represents some 60 to 100 million tons of organic waste.
The volume in France of sewage sludge, which, even in the unsorted state, in the presence of all non-fermentable impurities (sands, glasses, metals, etc.) can provide 106 liters of crude oil and 124 m3 of gas per tonne (Jean Lagarde, Science & Life, July 1949).
It is easy to see, sewage sludge, garbage, agricultural and agri-food waste would cover more than 10 times our oil needs in the traffic and transport sector ...
But other sources of organic matter are at our disposal. We think of algae, which, as already said, have the merit of "providing the indispensable iodine for the biological synthesis of oil. Algae are very prolific plants. It is in trillion tons that the annual production of algae is evaluated: for the only microscopic algae, this production is estimated at 200 billion tons ".
"Unlike mineral oil, the sources of fermentation oil are inexhaustible. "


Conclusion: neither thermolysis nor Fischer-Tropsch reactions. All the work is done by bacteria "bacillus perfringens" (one of the 4 species of bacteria responsible for gas gangrene).

exact, just a fermentation in a confined environment = without air (anaerobic).

"On average, a ton of fermented oil gives 800 liters of crude oil and 200 m3 fuel gas."
MMmmhh ..... what to leave dreamer!

A digester of this type can be used:

or a simple was and an inner tube, as for the alcoholic fermentation:

Well, if it's fermentation, it's even less revolutionary ... a bacterium or another ...

And then we will see them at the turn these American entrepreneurs who have always understood everything better than others at the blow of pompous pub ... by taking over the existing ...

That's why this is the most energy-consuming nation in the world ... and rolls all in Pick up or 4X4 V8 essence of 300 Ch :?

put oil

Unread Messageby tigrou_838 » 20/05/08, 10:50

salvation is all.

ok for the 200m3 fuel gas, we can use it quite easily,

but what to do with the 800litres of crude oil, would you have a refinement to make fuel easily usable ????? without consuming more energy than necessary.

thank you jonule for your great site.
