Weakly basic sorbent material reacting with all acidic gas components by salt formation (neutralization).
Basic chemical sorbent filter material.
Weakly basic reaction.
Neutralization point visible with colour indicator.
Fine purification agent for air and inert gases.
Removal of carbon dioxide (CO2) with very high uptake capacity (450 g CO2 per kg sorbent material)
Removal of acidic gases of low concentration, such as H2S, SO2, SO3, HCl, HBr, HJ, HF, F2, Cl2, Br2, NO, NOx etc.
The sorbent material is not suitable for purification of concentrated acidic gases, as it reacts immediately under high temperature build-up.
Regeneration is not possible

General Information Granular Material
Separation of solid or liquid particles out of gases.
Production of pure and purest reference and analysis gases by mechanical separation (filtration) as well as physical and chemical separation (adsorption and catalysis).
Fine gas purification is performed by catalysis and adsorption allowing reduction of contaminants up to few ppb.
