The γ-radiolysis of CO2 in packed vessels

Abstract

The γ-radiolysis of CO₂ has been studied in glass vessels packed with glass spheres of radii 8 × 10⁻³–2 × 10 ⁻⁵ m. The yields of CO were greater than in unpacked vessesls and an initial G(CO) = 4.1 was recorded for the finest packing. Baking the vessels in oxygen at 500–550°C resulted in a lowering of the CO yields but oxygen was a significant product under these circumstances. It is suggested that the results indicate deactivation, on the walls, of species responsible for CO re-oxidation.
