Hydrogen peroxide (H2O2) is an efficient oxidising agent, produced from hydrogen and atmospheric oxygen. The reactions take place in an organic solvent, which is circulated in the process, with palladium as a catalyst. In the first step hydrogen gas is added, and the solvent is hydrogenated. The second step is the oxidation where oxygen from the air is added. Hydrogen peroxide is formed.
In the third step hydrogen peroxide is extracted from the solvent with water and distilled to desired concentration, varying from 19-70wt%. Finally, a small quantity of stabiliser is added.The manufacturing of hydrogen peroxide takes place in Bohus and Alby, Sweden and in Rjukan, Norway.
