ABSTRACT:
A method for preparing and using compositions including a smectite clay and a base or base precursor which reacts with SO.sub.x in a hot flue gas is described. The base or base precursor is preferably the dispersed phase in the bulk phase of the clay. The compositions are heated to form the base which reacts with SO.sub.x in the flue gas.
