ABSTRACT:
Hot flue or process gases are cleaned utilizing an apparatus containing a barrier filter module formed of a monolithic ceramic support structure coated with a thin porous ceramic layer having a pore size of about 0.04-0.5 microns, and a catalyst module formed of a support structure coated with catalyst. The hot flue gases may be associated with a fluidized bed boiler plant, such as a circulating fluidized bed reactor. Gases to be cleaned are passed through the barrier filter module into contact with the thin porous ceramic layer, and then through the catalyst module so that there is a catalytic reaction with the gas.
