WERKWIJZE EN INRICHTING VOOR HET BEPALEN VAN HET OZONGEHALTE VAN OZONHOUDENDE GASMENGSELS.

摘要

The ozone content of ozone-containing gas mixtures is determined in a process wherein the ozone is converted to oxygen and which includes channeling a gas mixture containing nitrogen oxides and possibly water vapor through an adsorbent of aluminosilicate which contains 2 to 20% by weight of aluminum oxide and the aluminosilicate is of spherical shape with a particle diameter of 2 to 5 mm and a specific area of 200 to 650 m2/g and an average pore diameter of 5 to 10 nm.
