[Gasification] Tennessee company - pyrolysis biochar + hydrogen ($1.75 per gallon diesel-equivalent?)

[linvent at aol.com]

 In the case of making ammonia into urea, the CO2 is mixed with NH3 and steam over a catalyst to make urea, one of the most popular fertilizers. Ammonia is also run over a catalyst to produce nitric acid that is then reacted with other compounds, primarily acids to make the ammonia sulfate, nitrate, phosphate compounds, this comprises the majority of fertilizers sold.?

Dear Dr Karve 
 
Methane is CH4. The methane is compressed, heated and processed with steam 
(H2O) through a catalyst to produce CO and H2 in a "steam methane reformer". 
The gases are then passed through a water gas shift reactor where the CO 
reacts further with H2O to produce CO2 and more H2. The gases are cooled and 
passed through a pressure swing absorber where the hydrogen is separated 
from the remaining gas. CO2 and excess H2O are vented. 
 
In gasification, the reactions produce CO, CO2, H2 and H2O naturally. These 
are diluted with N2 if air is used. This syngas can be cleaned up and passed 
through a WGS reaction to convert the CO to CO2 and H2O to maximize H2 
production. 
 
Hope this helps...

Dear Greg, 
the major component of natural gas is methane. How does the fertilizer 
industry separate out hydrogen from methane? The process must be consuming a 
lot of energy.
