Abstract

High-temperature interactions of metal compound vapors with solids are important in processes like coal conversion, waste incineration, catalyst poisoning, chemical vapor deposition, and chemical vapor infiltration. In this study, the interactions of alkali-metal vapors with porous aluminosilicate solids are investigated. This system exhibits many general features of interactions of metal compound vapors with porous solids. In general, depending on the metal compound vapor concentration, two sorption mechanisms are possible: (a) direct reaction of metal vapor with the solid; (b) condensation in the pores of the solid and subsequent reaction of condensate with the solid. The important kinetic parameters for both mechanisms are determined. The fraction of alkali metal captured due to pore condensation increases with an increase in temperature. A theoretical model has been developed to simulate the processes of surface condensation, pore condensation, and chemical reaction occurring during interactions of saturated metal compound vapors with porous solids.
