Thanks Todd. Yep, I have looked at a search stream before, and have read
a significant amount, but have not found exactly what I was looking
for. But the link you sent on landfill gas is!! :)

Personally, no white papers in hand. But a Google search for
'Methane conversion Methanol' will give you weeks of bedtime
reading material. Even a few methods on how to produce acetic
acid, but unfortunately too much methanol is derived at the same
time...Go figger!

It kinda sounds like they are also using some type of
supercritical CO
method for oil extraction, thus leaving a somewhat clean
process.
Todd, you have links to any white papers on CO to Methanol
conversion? I
haven't had much success before.
Thanks,

All a bit elusive... quote:
Most methods of producing hydrogen burn another fuel for
energy,
which itself creates pollution - carbon monoxide, nitrogen
oxides
and other emissions, said Dr Dupont. Our catalyst uses
oxygen
from the air to heat up naturally, and this heat is used to
reform the oil with steam to create hydrogen. The excess
carbon
dioxide is taken into the second catalyst, then released for
storage or use in other chemical processes, ensuring that
damaging levels of CO2 aren't just put back into the
atmosphere.
Oxygen from the air to heat up naturally... Interesting. I
wonder what their loss rate of catalyst, or energy cost to
restore it if needed, or life cycle energy cost to refine it.
They mention pyrolysis in a latter paragraph. Wonder where
they
get the damaging levels of CO2? If they were using the
pyrolytic
fuels from the process itself to perpetuate stripping (not
creating) hydrogen they would be carbon neutral at worst,
erego
no damaging levels of CO2. Not to say that CO2 recovery is
not
intelligent, as it could be used to produce methanol as a
useable
byproduct, among other things.
