Zeolite Supply?
« on: February 10, 2011, 02:13:45 AM »
I've been searching google and a few of the major chemical suppliers but I can't really find a reliable source of "Zeolite 5A" which has the chemical formula Na12[(AlO2)12((SiO2)12].27H2O

I'm a mechanical engineer so I don't really know who the best suppliers are. Any recommendations?

Interesting stuff

Currently, the world’s annual production of natural zeolite is about 4 million tons. Of this quantity, 2.6 million tons are shipped to Chinese markets to be used in the concrete industry.

Is it that hard to find?

Certain kinds are hard to find. The one I'm looking for specifically absorbs things around the 5 angstrom range.

There's another one called "13x" that would be good too. It absorbs things less than 10 angstroms.

What I'm doing is trying to make a Pressure Swing Absorption system. Essentially, you put this 13X stuff in a container and then run air through it at high pressure. It removes the nitrogen leaving you with about 70-90% oxygen. If you lower the pressure, the nitrogen is released and you can re-use the material.
It's nothing new or special, but I need a LOT of oxygen so I have to build my own.

do you renew the Zeolite after passing air though it?
can it we recycled?

Yeah It's like a desiccant. Low pressures will released the trapped gasses.
Here's somebody's report that popped up on google.
