Dear Ken & List,
I agree with Ken that water is not a fuel AND its always good to define
what one is trying to do!
****Correct me if Im wrong!!!!!!****
Could we replace the steam with the exhaust gases (why make steam?)?
Are we not trying to do fuel reforming?
Charcoal is a catalyst that reduces the temperature needed (molecular
attraction?) to make H2 from water (CO from CO2 etc.?) and we would like
to use the waste heat from the IC engine to provide the necessary energy
((molecular vibrations (heat)) to facilitate this reaction. On the order
of the retort but the engine provides the heat. MAYBE the engine would
have enough quantity of heat (horizontal axis) BUT the catch would be the
rate of vibration ((temp.(vertical axis)).
So if we imagine what is going on: Our steam molecules are vibrating at a
high rate, heated from the engine, as they make their way to the reactor.
They encounter the hot charcoal and because of a high rate of molecular
vibration and molecular attraction they reassemble themselves into our H2
rich, and CO, gas. But if the rate of molecular vibration is too low they
will not rip themselves apart and reform.
The bottom line is that we do not want nitrogen to dilute our gas; hence
air blown, and we want the engine to provide the needed energy to
facilitate this reaction. Is that possible? I bet we would have to add
some higher level of heat. How about a microwave to push the reaction over
the top?
