<div class="moz-cite-prefix">Thanks, Tom.<br>
<br>
Good to know about the ICM gasifiers (Wichita, Kansas?)<br>
It is a company I had not paid very much attention to... even
though Jon Orr had connected with the CBI back in mid-2011.<br>
Are they the ones involved with the GEVO tech? (for making JET
FUEL... and Butanol from, for instance, Corn Ethanol Co-Products)<br>
<br>
Do you happen to know anything about <i>Sierra Energy</i>'s
Gasification (the tech described in the original <a
href="http://www.nytimes.com/2013/08/18/business/trash-into-gas-efficiently-an-army-test-may-tell.html">NY
Times article</a> that Metta sent)? I had not heard about this
company before, yet here we have it being tested by the <i>US
Army</i>...<br>

style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">When
we pyrolyze plastics or trash we usually wind up with char
that is a hazardous waste. It must be disposed of at a high
cost, typically $600/ton, in a hazardous landfill, or
further processed for disposal in a lower cost - $80/ton –
landfill. It is not suitable for use as biochar. Recent
studies in Japan of the pyrogenetic characteristics of
molten slag from waste pyrolysis have sought to refine ash
quality but it does not contain carbon. <o:p></o:p></span></p>

style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Gasification
is the conversion of a solid primarily to gas. The char-ash
residue is not the principal product. As Lloyd says there
have been many waste gasification systems. You will find
example of waste gasification projects funded by the US
government from about the 1970s readily on the internet.
Oxygen blown past furnaces were among the early technologies
applied to waste. The Purox (Union Carbide) process, still
in use in Japan, comes to mind. A few years ago the Purox
process was considered for the city of Indianapolis for
waste. More recently Westinghouse plasma gasifiers are
gasifying waste in India and Turkey. Oxygen is burned in the
plasma guns that heat a bed of coke. The waste gasifies as
it is partly heated by the plasma. Ash melts and drip
through the coke. One major ethanol project considered using
the Westinghouse plasma gasifier to produce syngas for
conversion to ethanol. All of the carbon is consumed in the
process. The ash in the blast furnace environment was
sometimes converted to glass, as in the Andco-Torrax 100 tpd
pilot gasifier operated for several years at the Disney
World. In that process pyrolysis gas was oxidized to melt
the ash to glass. I remember that refractory wear was a
problem in that plant. Refractory wear is a challenge in
waste and coal gasification and has been studied extensively
in the US. <o:p></o:p></span></p>

style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Gasification
and pyrolysis processes for waste should not be discounted
for producing biochar. When used with cleaner biomass they
make very good char. The gasifier that is built by ICM was
originally designed by a Boeing engineer who developed the
gasifier for waste gasification. (Boeing did more than build
planes. We worked on a Boeing designed refuse derived fuel
plant in the 1980s. ) ICM bought or leased the patent from
the inventor. ICM has demonstrated that when used with crop
residues and urban wood wastes it produces a very good char.
They can make either ash or biochar. They applied field
tests for Iowa State University. It is a technology that is
waiting for suitable markets for heat, power and biochar for
200-400 tpd fuel input. <o:p></o:p></span></p>

Trash --> Char does NOT equal "Biochar". [!] I would
NEVER recommend using the stuff in soils...<br>
<br>
<i>Sierra Energy</i>'s Gasification. Also (probably) <u>not</u>
that NEW. There are many, many, many Gasification systems
out there that make 'syngas' (hydrogen and carbon monoxide)
~ and can do things <i>similar</i> to this, although this
does seem a bit "unique"... because of this so called "<i>FastOx</i>
chemical reaction". [?]<br>
<br>
Best thing to do is probably to ask the folks on the
"Gasification List"... (CC'd)<br>
