Subject: Re: [Gasification] Syngas on Wiki_<br>
<br></div><div><div></div><div class="h5">
I believe that syngas is specific to the application, and is based on the<br>
ratio of hydrogen to carbon monoxide. As an example, ammonia syngas as<br>
defined in flow sheets for an ammonia plant is 3H2:1N2. Syngas for FT<br>
reactions<br>
can be from .6H2:1CO-1.5H2:CO, with iron based catalysts requiring less H2<br>
than cobalt catalysts because the iron catalyst will do it's own shift<br>
reaction. Produced gas, water gas, blue gas, low heating value gas, low CV<br>
gas are<br>
all more appropriate designations for air based gasification systems. Even<br>
an<br>
oxygen or steam driven gasification system will not produce a "syngas"<br>
appropriate for certain catalyst reactions, but will work for many.<br>
<br>
The use of nitrogen in the gas is indeed done in some of the more<br>
sopshisticated catalyst systems because it reduces the thermal concentration<br>
in the<br>
typically exothermic reactor such as FT reactions which in turn reduces the<br>
amount of cooling needed for the reactor design which can be a significant<br>
effect.<br>
<br>
The use of the term "syngas" is inappropriate for any gasification system<br>
because it is a specific composition based on the catalyst used. Only syngas<br>
<br>
can be called this when it is cleaned, balanced for the catalyst with<br>
contaminants removed such as Cl, S, organics so that the catalyst is not<br>
damaged<br>
by it.<br>
