[Gasification] Gasification Digest, Vol 19, Issue 10

Dear Andrew,
 
If you don't mind, while you still have your teaching hat on, couldn't hydrogen be seperated from other gasifier products by filling a sutable vessel with the mixture, and just waiting a long time until the hydrogen alone leaks out? The leaked hydrogen could be collected in a surrounding vessel constructed of different material. I understand hydrogen particles are very small. My brothers and, I used to capture hydrogen in toy balloons from hydrocloric acid attacking old steel nails we found. We noted the balloons no longer floated in air after a day or so :(

No because all materials in a gaseous state exert a partial pressure, this means all the individual molecules freely intermingle and mix in proportions to their partial pressure in the mixture.   AJH
