Garcia-Mallol, J A; Sinn, B T

A method is described of operating a fluidized bed combustion reactor comprising the steps of disposing on a perforated plate bed of particulate material including a sulfur adsorbent material and a combustible material, introducing air through the plate and into the bed to fluidize and promote the combustion of the materials, and providing an exit for combustion gases which would normally entrain a portion of the materials as the gases pass through the bed; wherein the improvement comprises the step of introducing additional particulate material to the bed. The additional particulate material is of a different composition than the sulfur adsorbent material and the combustible material and being of a particulate size less than the particulate size of the sulfur adsorbent material and combustible material so that the additional particulate material is neither sulfur adsorbent or combustible and is entrained in the gases while the sulfur adsorbent material and combustible material are maintained in the bed.
