Pyrolysis of waste by the sun

[toto65]

Hello everybody

I gathered ideas to imagine a recovery unit of household waste and industrial waste.
Well this is only a reflection, I do not pretend to invent anything. No doubt other people have already thought about it.

The idea is to use the heat of the sun to achieve the thermolysis of waste. Then by the Fischer-Tropsch process to turn the gases into fuel.

What do you think?

Schematic diagram:

The interest is to have a cost of the raw material positive.
To have a variable thermolysis unit load and very flexible.

The negative point is the hazards of meteorology.
For this it will take a possibility of storing OM.

yes there are things like that which will be done in industrial quantities when the oil will be more expensive ...


while I am working I work in smaller on a wood gasifier accepting a bit of waste and whose performance can be improved by solar heat when there is some

the integration of solar heat with a gas generator is more profitable than to pass this solar heat in a steam engine

The idea is superb but these processes must be treated with the least possible complexity.

Let me explain :
- why end up with scrap metal and glass in garbage cans, when do an effective sorting is within the reach of the first child of 10 years (yes German if you want because in France it still does not pass )?
- why have a huge and unique treatment center when a part of treatment can and must be done internally (glass recovery, metal recovery, methanisation at home ...)?

I know that the process that you present will sometimes be inevitable (for the sludge of purification plants units for example ...), and it has on this point the merit to treat very cleverly all the waste, and with minimal cost medium term. But I hope that in any case where centralized management process can be avoided, people are responsible enough and empowered to avoid it.

I agree on this point Chatelot working on a gasifier for partial combustion of waste at home. Anything that is not likely to make significant toxic releases does not deserve to go to landfill.

By cons, for storage, do not worry, it already exists for gas thermolysis. Just change the plant a little to switch to solar thermolysis ...

Hello Chatelot, Mingui!

And especially, A nod to Toto65, a beautiful initiative with a splendid illustration and excellent links.
First of all, I can give you here a good link on the state of art of gasogens, and more generally pyrolysis / thermolysis, which although cousins, do not have exactly the same vocation and therefore the same operation.

The file is big, but worth it for people who like "the technical".

To please everyone, the PHRSD works both centrally and decentralized, and in pyrolysis and thermolysis. He also does many other things, see:
http://sycomoreen.free.fr/PHRSD_FAQ.html

Of course, it takes sun ... say that the South of France has a resource already very important.

It is clear that thermolysis and pyrolysis indirectly burn part of the waste (removal of a portion of the gas generated) to ensure their operation. The PHRSD intervenes by supply of free heat to tend towards a total valorization of the waste.

Another not insignificant advantage, the very high temperatures make it possible to crack all the tars and to eliminate the "bottom ash" frequently blocking the thermolysis installations below 1000 ° C.

One last idea; There is a lot of talk about Fischer Tropsch for BioDiesel, however, we are able to synthesize a large amount of methanol from syngas of high temperature thermolysis (CO + H2). See this link:
http://books.google.fr/books?id=8dSeVDp ... &ct=result

Methanol is an excellent gasoline for the automobile: it is liquid up to 60 ° C and rejects extremely little CO2 because it is low carbon. Its ideal combustion gives 1 CO2 and water !!

See you soon !

To couple with this type of solar oven quite simple, but with high concentration for 900 ° C, to make the pyrolysis, to make lime, electric current with Stirling at high temperature, locally, etc ...:

Another great idea made in Econology !!
