GAS-L: Tin liguid metal H2 producer -- The Good links




OK Folks --

In regards to liquid tin metal baths -- production of pure H2 -- sparging
with CO -- making methane by cooking any biomass in an H2 rich atmosphere
-- etc.

After a little checking.

Here is the exact Url for a PDF file that lays it all on the line.

http://www.alchemix.us/hydromax.pdf

Only 212 KB ---

"Highlightening" the point of interest ot this list:

"The flexibility to use biomass as a feedstock provides a large source of
renewable energy that yields no net increase in carbon dioxide emissions."

Quoting from the PDF -- we see there has been some "changes":

**********************
After some experimentation, Alchemix has selected a mixture of iron and
tin. Iron strongly attracts the oxygen in steam to form iron oxide. The
iron oxide is then reduced back to iron by reacting with carbon and air.
Carbon dioxide is formed in this process. The tin does not oxidize but
allows operation at lower temperatures and helps to remove sulfur at low
cost. The following simplified Figure 1 diagram shows the principal reactions.
**********************

Cute!! Also in that PDF you have complete specs and costs to build a
"gas-plant" -- still to big and to rich for my blood.

Here is the "summary"

*********************
SUMMARY

Hydrogen is now the focus of intense international interest due to current
efforts to develop fuel cells for clean transportation and distributed
power generation. However, hydrogen must first be made available in large
quantities to supply the hydrogen fuel when needed. Alchemix has developed
the HydroMax process to produce hydrogen at low cost from steam and carbon
sources such as coal, petroleum coke and biomass. HydroMax plants can
provide the additional hydrogen needed by oil refineries today to refine
and desulfurize increasingly heavy crude oils to progressively more
stringent specifications. 

Later, these same plants can be converted to produce hydrogen as demand
warrants. 

These multiple capabilities insure that the HydroMax Technologies can
provide the bridge to a hydrogen based economy. There is a compelling case
to be made politically, environmentally and economically for the adaptation
of the HydroMax technology. The ability to convert high sulfur coal into
hydrogen or syngas cleanly and economically provides a path to energy
independence for coal-rich, oil-poor nations such as the United States,
China, India and Indonesia. 

The flexibility to use biomass as a feedstock provides a large source of
renewable energy that yields no net increase in carbon dioxide emissions.

Alchemix is currently soliciting help to build an intermediate size
demonstration plant which will prove the scalability of the HydroMax
Technologies. After this plant has been in operation for about six months,
full scale commercial plants of virtually any size can be built.

Further -- they have a movie of their apparatus in operation -- 6.4 megs:

To much for me to download.

Happier now Arnt??
