The production of methane without the use of organics was solved 100 years ago by "Sabatier" A French Nobel prize winner for his contribution to inorganic chemistry. He produced the gas using CO 2+ H 2 in a pressure heat reaction in the presence of metallic catalysts. If you compare his original work with the contributions made by various crackpot free energy workers who run IC engines on water, you will notice the similarities of the process they employ. The engines used to demonstrate the apparent miracle have a modified cylinder head with catylist plates internally attached. Using some of the hot CO + CO 2 exhaust together with steam to provide O + H 2 to provide "FUEL" to the engine The "Sabatier" Reaction occurs during the power stroke of the engine. The exhaust manifold of an engine running at peak load produces enough heat to gasify any hydrogen bearing fuel in an oxygen free enclosure, Thus utilizing waste heat for the purpose of making fuel. Forget about building a fuel burning gas converter running on a negative pressure. use a high compression engine to provide the conditions to change CO 2 into methane using low grade fuels. Enter: non organic methane generation: in your seach engine. GFWHELL In a message dated 4/2/2015 10:25:38 P.M. Eastern Daylight Time, [email protected] writes:
Not sure what is involved in methane, other than filling a tank with manure and water and waiting (with nose plugs<grin> ) - but on a small scale I wonder what kind of volumes of methane are produced. If you take a typical small 5 kw generator (10hp engine) and figure it has a cylinder volume around 400cc and it is turning 3600 rpm you would be looking at .4lt * 1800=720 litres/minute or about 25.4 cfm of gas. Even if you mix it 10:1 with air, you are using 2.5 cfm of methane, 150 cubic feet per hour. How many minutes will a small digester run that engine? (or how big does the digester have to be to keep the engine running as long as you want it.) Flaring a small digester may be impressive, but what is the actual volume of gas it provides? With wood gasification you can "create" your fuel as fast as you need it simply by sizing the gasifier to match your engine and pouring in more wood chips or pellets. Suggest spending a few weeks reading through the back postings here, on yahoo woodgas group and look at drive on wood (although that may be a pay site). You'll soon figure out who knows what they are talking about, and you can follow some of them back to their web sites for more info.
