Making mineral fuel ?

Externet - 7-10-2005 at 20:30

Hi.
Using one or more of these reasonably pure abundant natural soils :

Lime
Chalk
Salt
Coal
Silica
Water
Silicates of calcium
Silicates of aluminum
Silicates of magnesium
Silicates of iron
Sulfates of calcium
Sulfates of barium
Sulfates of strontium
Chlorides of calcium
Chlorides of potassium
Chlorides of ammonium
Calcium fluoride
Nitrate of ammonium
Nitrate of potassium

plus heat plus some other requiered compound if needed, what mineral fuels could you come up with ?
Example: Coal + lime + heat = calcium carbide -yields acetylene fuel-

I think this is the wrong forum for this.

If you plan to make fossil fuel, good luck, it take pressure and time.
Pressure can be reproduced easily, but we have short supply of laboratory time.

Well a fuel is a reducer due to our oxidizing atmosphere, and the only reducer on the list is coal, so any process to make a fuel would have to involve coal. That said, take your pick...just about anything, after having been reduced by carbon, can be re-oxidized with a release of heat, as more or less defines a fuel.

If its fuel you want look no further

This site covers 50 years of research on synth.fuels with 57.5 gigs of books for study.It took me 1 1/2 weeks to download the whole thing,so I dont think you will run out of things to think about.And one more link just incase you want to DIY

I hope these links help.

So what's in this woodgas from your second link? My guess would be CO, H2, and CH4?

The hot wood gasses are more easily examined if they can be kept separate from the combustion gasses of the fire. This can be done by cooking a small quantity of wood in a test tube, and then cooling those gasses as they pass through a water bath (Figure 1). Cooling causes the creosotes, light oils, water vapor, methanol, and many other chemicals to drop out of the gas. What remains is largely CO with small percentages of H2, CH4, CO2, N2 and various other gasses that give it a very pungent odor. It burns with a pale blue flame, producing largely CO2.


Could be an interesting way to get certain things (especially like MeOH) which some members in certain places cannot get.

one more idea

If I am correct there is a ebook on bio-oil on axehandles ftp.what makes this worth reading is the book covers a process that produces 42 chemicals from wood or other bio-mass. Here is a link on bio-oil that may get you started.
