Alkalized alumina (an active form of sodium aluminate) has been considered as a sorbent for the removal of sulfur dioxide from industrial flue gases. Four rate equations, each based on a different mechanism, were compared with the results of thin-bed sorption tests. It was found that each equation agreed with the experimental results, within experimental variance, over most of the range of sorption studied. First-order rate equations were generally satisfactory in explaining both sorption and regeneration. It is concluded that the equations developed are adequate for the design of commercial fluidized beds for the sorption of so2 from industrial flue gases and regeneration of the alkalized alumina.
