    摘要： A charged adsorbent is accommodated in a desorbing vessel and in an intermediate container which communicates with the desorbing vessel. The charged adsorbent is desorbed in the desorbing vessel by contacting the same with a heat carrier, such as with hot sand, and a desorption gas which develops during the desorption of the charged adsorbent in the desorbing vessel is passed through the charged adsorbent accommodated in the intermediate container to capture at least one component of the desorption gas in the charged adsorbent present in the intermediate container. The purified desorption gas is withdrawn from the intermediate container, and the regenerated adsorbent is gradually discharged from the desorbing vessel and the supply of the adsorbent in the desorbing vessel is replenished by charged adsorbent from the intermediate container. The desorption gas is cooled during the passage thereof through the charged adsorbent present in the intermediate container. The magnitude of the temperature reduction of the desorption gas may be controlled by controlling the rate at which the desorption gas is discharged from the intermediate container, such as by resorting to the use of an adjustable vane. The adsorbent in the intermediate container may be confined by gas-permeable walls through which the desorption gas enters and leaves the adsorbent present in the intermediate container.

    摘要： A gaseous substance such as a flue gas or a combustion gas contains an adsorbable impurity which is capable of undergoing an exothermic reaction in the presence of oxygen. The gaseous substance is passed into an adsorber via an inlet conduit. In the adsorber, the impurity in the gaseous substance is adsorbed therefrom. The purified gaseous substance is withdrawn from the adsorber therefrom. The purified gaseous substance is withdrawn from the adsorber via an outlet conduit and conveyed to an exhaust stack. The adsorption of the impurity, as well as the reaction thereof with oxygen in the adsorber, liberate heat. The liberated heat is conveyed from the adsorber by the gaseous substance which is being purified and, accordingly, no undue temperature increase, which may harm or even cause combustion of the adsorbent, occurs in the adsorber. The operation of purifying the gaseous substance is carried out at an underpressure so that, when passage of the gaseous substance through the adsorber is interrupted for some reason, currents of air tend to be drawn through the adsorber due to the suction effects generated in the inlet and outlet conduits. The currents of air constitute sources of fresh oxygen and, as a result, reaction of the adsorbed impurity can continue. The liberated heat is no longer removed, however, so that a drastic temperature increase will then occur in the adsorber. To avoid this, a pair of spaced butterfly valves is provided in both the inlet and outlet conduits. The butterfly valves close, although not with absolute gastightness, when the passage of the gaseous substance through the adsorber is interrupted. This reduces the suction effects. Air or an inert gas is admitted into the regions between the respective pairs of butterfly valves until a pressure on the order of atmospheric pressure has been reached in these regions. The air or inert gas serves as a sort of buffer which prevents the suction effects generated by the source of the gaseous substance and the exhaust stack from acting on the adsorber. Although the air or inert gas may leak into the adsorber until atmospheric pressure has been reached in the latter, any oxygen introduced in this manner is quickly used up so that only minimal temperature increases occur in the adsorber.

    摘要： A reaction vessel for regenerating particulate adsorbents has a bottom outlet and top inlets for admission of the adsorbent to be regenerated by being heated to a regeneration temperature, and for a particulate regenerating material at a temperature above the regeneration temperature. The mixture of the adsorbent with the regenerating material forms a bed in the reaction vessel and is continuously withdrawn through the outlet so that the bed descends toward the latter and is replenished from above under the formation of a cone at the upper region of the bed. A plurality of tubular baffles coaxially surrounds the inlets which are also coaxial with one another, each of the tubular baffles penetrating into the bed in the region of the cone and retards the flow of the particles of the mixture down the slope of the cone in that the particles must pass underneath the baffle to flow to the next baffle. The bed may be confined between a plurality of axially overlapping spaced tubular guide baffles located in the interior of the reaction vessel with a spacing therefrom. At least one partition may be provided between one of the guide baffles and the vessel, subdividing the chamber between the vessel and the guide baffles into two compartments from which gases which develop during the regeneration of the adsorbent are separately exhausted.

    摘要： Sulfur oxides and nitrogen oxides are removed from exhaust gases containing additionally oxygen and steam, by the addition of gaseous ammonia at temperatures between about 110.degree. and 180.degree. C. The exhaust gases travel in the interior of a reactor across a travelling bed which goes from above to below, composed of granulated, carbon-containing adsorbent with or without catalysts. In the first travelling bed initially a large portion of the sulfur oxides is adsorptively removed. In the second travelling bed after dosed addition of gaseous ammonia the nitrogen oxides are catalytically reduced to nitrogen as well as further sulfur oxides being separated. The improvement involves extending the path of the exhaust gases between the first and the second travelling beds and introducing into the volume of the exhaust gas stream between the travelling beds a forced mixture of dosed added ammonia with the exhaust gas departing from the first travelling bed.

    摘要： A process for manufacturing a carbon catalyst for use in NO.sub.x reduction with ammonia catalyzed by active carbons and active cokes is described. The new carbon catalyst exhibits improved catalytic activity and hence a higher yield in NO. In the manufacturing process, a mixture of ground, oxidized hard coal and binders is moulded, carbonized at temperatures between 700.degree. and 900.degree. C., and then activated with steam at a temperature of 800.degree. to 850.degree. C. for 45 to 100 minutes, until a degree of activation of 5 to 15% is obtained.
