摘要：

Five basic macroreticular ion-exchange resins have been evaluated as adsorbents for small-scale flue gas desulfurization. The mechanical and thermal stabilities of these resins have been measured, and a weak-base resin with suitable stability characteristics has been identified. The adsorption capacities of this resin for sulfur dioxide, nitrogen dioxide, and carbon dioxide have been determined at two temperatures and up to a pressure of 120 kPa. The adsorption data have been analyzed with the Langmuir, loading ratio, and vacancy solution models. On the basis of these analyses, the mechanism of adsorption has been discussed, and the adsorption behavior of mixtures of these gases has been predicted. © 1990, American Chemical Society.
