Kinetics of Absorption of Carbon Dioxide and Sulfur Dioxide in Fluorine-Containing Media

It has been established that the reactions of sulfur dioxide oxidation and carbon dioxide conversion take place in aqueous suspensions of calcium fluoride at room temperature and atmospheric pressure. The optimal flow rates of gases and concentration of calcium fluoride suspension for their maximum...

Description
Summary:It has been established that the reactions of sulfur dioxide oxidation and carbon dioxide conversion take place in aqueous suspensions of calcium fluoride at room temperature and atmospheric pressure. The optimal flow rates of gases and concentration of calcium fluoride suspension for their maximum absorption were determined. It has been shown that the suspension of CaF 2 can be repeatedly used after its regeneration with atmospheric oxygen.
