Abstract
A process for the treatment of a gas stream by passing the gas stream parallel to the outer screen of a contactor bed wherein the detrimental effects caused by the accumulation of fine particles on the screen is counteracted by the periodic or continuous admixture of additional fluidizable particles into the gas stream. The invention may be adapted to many processes in which a particle-containing gas stream is treated using a parallel flow vapor-solids contacting apparatus including the adsorption of specific chemical compounds, the oxidation of sulfur-containing compounds or the reduction of nitrogen oxides.
