DUST RETARDATION STUDIES OF CARBON DIOXIDE SORBENTS
Abstract
Surfaces of carbon dioxide sorbent granules were treated with various liquid preparations to diminish dusting tendency and to improve carbon dioxide capacity. Emphasis was placed on a screening program whereby granules of lithium hydroxide were impregnated with solutions of surfactants, organic polymers, and lithium halide salts. Relative effectiveness of treatment was evaluated using a carbon dioxide dynamic capacity test and a dust test. Studies show that latex emulsions significantly diminish dusting tendency of lithium hydroxide granules with only negligible loss in carbon dioxide sorption capacity. Lithium chloride-treated lithium hydroxide results in significantly improved carbon dioxide capacity at low humidity, but such treatment is generally less effective as a deduster than the latex preparation. Excess loadings of surfactants were required to diminish dusting to acceptable limits.
