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.
