ABSTRACT:
A process of removing pollutants from exhaust gases in a circulating fluidized bed, in which solids are circulated through a fluidized bed reactor, separated in a separator and returned via a return line, to the reactor. The exhaust gas is introduced as a fluidizing gas into a fluidized bed which consists of two solid fractions differing in particle size, namely, a coarse-grained fraction having a particle size d.sub.p 50 in the range of 150 to 500 microns and a fine-grained fraction having a particle size d.sub.p 50 below 10 microns.
