<div> <font class="Apple-style-span" color="#000000" face="arial"><span class="Apple-style-span" style="font-size: small;">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. </span></font></div>

<pre style="font-size: 9pt;"><tt>Dear Dr Karve <br>
<br>
Methane is CH4. The methane is compressed, heated and processed with steam <br>
(H2O) through a catalyst to produce CO and H2 in a "steam methane reformer". <br>
The gases are then passed through a water gas shift reactor where the CO <br>
reacts further with H2O to produce CO2 and more H2. The gases are cooled and <br>
passed through a pressure swing absorber where the hydrogen is separated <br>
from the remaining gas. CO2 and excess H2O are vented. <br>
<br>
In gasification, the reactions produce CO, CO2, H2 and H2O naturally. These <br>
are diluted with N2 if air is used. This syngas can be cleaned up and passed <br>
through a WGS reaction to convert the CO to CO2 and H2O to maximize H2 <br>
production. <br>
<br>
Hope this helps... <br>

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