New process for the production of ammonia!

Hello,

I found some interesting material.
New process for the production of ammonia!

Today the ammonia produced from electricity is obtained with an overall energy yield (electricity -> H2 -> NH3 - 2 ° link) of about 50%!
The energy contained in the ammonia is about 21000 kj / kg in hydrogen that can be used with systems with high efficiency (turbogas or fuel cells) ...

Question.
Nuclear energy does not have the problem of providing electricity during the night? ...

Hi Titjus,

first of all, I do not know if a moderator can change processes in process because the meaning is not the same :D

Thank you for your link.


The ideal ammonia combustion of ammonia
NH3 + 5/4 O2 -> NO2 + 3/2 H2O

generates NOx that is not bearable in the city and must be sequestered in an industrial environment. Many other nitrous gases dangerous or aggressive for the respiratory system are present as NO, N2O, etc ...

Here is a link that talks about its use in fuel on internal combustion engine (ouch, very good for children in the city :frown: ):

Good evening Remundo,


better use ammonia to store hydrogen.
1 kg of ammonia produces approximately 2 m3 of hydrogen according to the following reaction 2NH3 -> 3H2 + N2 (hentalpy = 30 kj / mol of hydrogen produced that can be easily recovered ...).

2H2 + O2 -> 2H20 60% efficiency (with turbogas or fuel cells)

Ah, you're using it as storage. This may be useful because NH3 does not diffuse like H2 through metals : Idea:
