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

[Rex Zietsman]

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...

Rex Zietsman

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.
