catalytic converter
An apparatus for treatment of a human body having an enclosure equipped with an inlet and outlet is described wherein the inlet is in fluid communication with a source of liquid under pressure. A portion of the enclosure is provided with an open treatment zone. Opposite the inlet is an obstacle such as an impeller to create turbulence in the treatment zone.

4377066 POLLUTION-FREE PRESSURIZED FLUIDIZED BED COMBUSTION UTILIZING A HIGH CONCENTRATION OF W A T E R VAPOR
A process of purifying exhaust air which contains organic pollutants, particularly exhaust air from paint-drying operations, comprises adsorption on particulate activated carbon, which is contained in a fixed bed and from which at least part of the adsorbate can be desorbed. The activated carbon has a particle size in the range of about 2 to 6 mm, a bulk density of 250 to 450 g/1 and B.E.T. surface area of 800 to 1800 m2/g and the activated carbon is subjected to a desorbing treatment with steam while the bed of activated carbon is maintained at temperatures of 100 degrees to 150 degrees C.

4378307 POLLUTION CONTROL CATALYST FOR I N T E R N A L COMBUSTION ENGINE EXHAUST SYSTEM/CATALYTIC CONVERTER
A continuous process for the combustion of solid fuels in a fluidized bed of solid particles under conditions such that flue gas is essentially free of dust and oxides of sulfur and nitrogen. Fuel is charged as an aqueous slurry and additional water condensed from the flue gas is recycled to the combustion zone. Combustion is promoted both by water vapor and alkali added with fuel slurry, while the alkali serves also to neutralize and remove sulfur in completely oxidized, or sulfate, form. Useful heat is recovered from the hot gases leaving the combustion zone and, in some cases, from the fluidized bed itself. Under the pressure of the system recovery of heat results in condensation of water which serves to scrub dust from the flue gas, slurry product ash and furnish recycle water, which controls reac-
