Abstract
The influence of the geometry and materials of a plasma reactor on the oxidation of propylene in the presence of water has been studied. One- and two-barrier discharge cells with coaxial and planar arrangement of electrodes have been considered, with the dielectric barriers being made of Pyrex glass or fiberglass laminate. It has been shown that the geometry and material of the reactor electrodes do not significantly affect the composition and amount of the products. The main products of propylene oxidation are compounds with the general formula C3HxO, C1–C4 hydrocarbon gases, methanol, and acetaldehyde. Hydrogen peroxide and nitrate ions were identified in the aqueous solution; the pH of the solution changed from 7 to 3. For the reactor with one dielectric barrier, metals from the electrode surface have been found to be slightly carried over into the aqueous solution.
