This work presents a study on the capacity of oil shale ash to remove
sulphur dioxide from air streams before escaping into the atmosphere. Slurries of
different concentrations of this ash showed an uptake capacity of 4 10??4 mol
SO2/g ash obtained after 250 sec. This value increases with the increase of solution
pH, temperature, and ash concentration, and decreases the ash particle size. The
process of uptake seems to be coupled with both adsorption of SO2??
3 on the surface
of metal oxides and reaction with alkali and alkali earth metal hydroxides.
