[Gasification] O2 - N

I know there are some very bright people on this list, Peter has mentioned: ?research!research!



Zeolite comes in many forms. naturally mined or manufactured.
The characteristics of these materials, can be refined to suit the filtration of most gasses.
With a twin tower arrangement and the correct?material it should be possible to remove one gas from another.
This could be turned into a much sought after super filtration system and gas purification unit which is easy and relatively cheap to construct.
Its uses could include the removal of N2 or O2 or both in one pass. It could remove H2 from CO2 or CO from CO2
The machine I built was nothing more than two pieces of 6" galvanized water pipe with end caps. about 14 lb of Molecular sieve, a change over valve, electric timer and some pipe and fittings.? I designed this unit along previous designs for the removal of water from the air stream.?I ordered the Sieve to suit.
?This unit, provides 120 psi Air @24cuft pm of -60 deg f or better, to purge the optical cavities of a C.N.C Laser cutting machine capable of cutting 1/2" steel plate.
Now I know that Biomass derived gas requires quite a clean up before it can be used for any thing other than a flare.

Traces of tar or oil could not be passed through such a gas ?refining system.
There are other methods?for the removal of these unwanted contaminants, and to this end I refer back to the patent office.
I suggest that we all use this resource, to find the keys to our problems. The reason being: these problems are not new. and have probably already been addressed in one form or another.For instance:Turning crude oil into producer gas or water gas in a continuous stream. no trace of tar afterwards!?The process we require is more than half way down line. we don't need the first half just the gas refinement part.
