Removal of SO₂ from gases on carbon materials

The aim of the work is to describe a capability of the active carbon CARBON L-2-4 (AC) and of the nanocarbon (NC) materials containing iron nanoparticles to continuously remove SO₂ from air. The carbon nanomaterials (NC) containing iron nanoparticles were synthesised using a chemical vapor deposition method - through catalytic decomposition of ethylene on nanocrystalline iron.

The process of SO₂ removal was carried out on dry and wet with water carbon catalyst (AC or NC) and was studied for inlet SO₂ concentration 0.3 vol.% in the presence of O₂, N₂ and H₂O, in the temperature range of 40-80°C.
