[Gasification] Exclusion of nitrogen from air

[GFWHELL at aol.com]

I am interested in producing O 3 or O  4 For use as a sanitizer. I  have 
had some success in producing this short lived gas using ionization with  high 
voltage and glass covered electrodes.
The ionization of gasses using selective frequencies may have some use in  
the gasification field.
I suppose O3 is higher on the energy scale than O as it seems more  
reactive, I am wondering if O 3 would have any effect in a pyrolitic reaction. 
Cracking water at high temperature necessitates the production of an oxide  
in order to free the hydrogen.
Ionizing hot gasses in the presence of a suitable catalyst might possibly  
increase the hyrdogen content of the gas. 
I assume if you produce CO 3 , it will eventually turn into C O2  +  O?

Dear  Anand and all:

Your question below on molecular sieves opened a LARGE  box in the attic of 
my mind.

In 1952 I worked for the Linde Air  (oxygen) Company, now Praxis Air.  They 
make and sell liquid nitrogen,  oxygen and air by the truckload!

My degree is in x-ray  crystallography,  determining the structure of 
molecules from their x-ray  diffraction patterns.  My first job was to understand 
how oxygen cut  steel in a torch process widely used since 1900, but I 
played bridge at  lunchtime with another group working on molecular sieves.  

One  day one partner was missing, so I asked the others what they were 
working  on.  They said they were developing "Molecular Sieves".  These are  
three dimensional alumina-silicate minerals now found in nature and  
manufactured for catalysts.  They told me that they hoped to be able to  separate 
oxygen from nirogen using such a sieve.  

They were  successful.   One often sees people dragging a small cart which  
makes 90% oxygen from air for those with difficulty breathing.

The "A" sieve is one of the  most widely used.  I asked my friends what the 
structure of the sieve  was.  They told me that Linus Pauling was one of 
their consultants, and  that he told them it might take years to work out the 
structure, and that they  would need to have a "single crystal", rather than 
the powder available.   

I took this as a challenge, and worked out the structure on my own  time.  
I was given a $5,000 prize by the Liinde Company for the work, and  we 
published in the Journal of the American Chemical Society (JACS) in the mid  
1950s.  

The A sieve has a 10 Angstrom cubic unit cell that has a  6 Angstrom 
"window" in each of the six faces of the cube.  I have 25 lb  in my lab that I 
bought a year ago.  I have doped each unit cell with a  few atoms of iron, and 
hope that it will be a superior catalyst for making  ammonia (Haber-Bosch 
process) or oil (Fischer-Tropsch process).

I have  two colleagues that I sent samples of the sieve for testing, AND I 
AM WAITING  for their reports.  

If anyone else is interested, write me.

heats up the nitrogen in the air. This nitrogen ultimately goes  out of the 
chimney, taking with it a lot of heat. The technologies based on  wood as 
fuel are pretty old, but one can revive them, using some of the more  recent 
techniques. A person who owns a foundry told me that a moleular sieve  was now 
available for separating nitrogen from oxygen. Has anybody heard of  it? 
Can it be used in producing a better stove and a better gasifier?
