    摘要： The present invention is directed to a method of controlling the condensation of sulfur trioxide in flue gases to thereby inhibit the corrosion of metallic parts because of the sulfuric acid inherently formed. Basically, the requirements on the addition of particulate alumina (Al2O3) to the flue gas at a place where it is experiencing turbulence, and where its temperature is below 1000* F, and preferably within the range of 450* F. to 650* F.

    摘要： AN APPARATUS AND A PROCESS WHEREIN A SOLID-LIQUID SLURRY IS CIRCULATED IN A VERTICAL REACTOR BY MEANS OF GAS LIFT ACTION IN A CENTRALLY LOCATED TUBE INSIDE THE REACTOR. ONE OR MORE HYDROCYCLONES ARE USED TO CLARIFY LIQUID PRODUCT LEAVING THE REACTOR AND TO RETURN SLURRY SOLIDS TO THE REACTOR. THE PROCESS IS PARTICULARLY DESIRABLE FOR CATALYTICALLY DESULFUIZING RESIDUAL OILS IN THE PRESENCE OF HYDROGEN.

    摘要： WASTE STACK GASES OR OTHER GASES CONTAINING SULFUR DIOXIDE GAS ARE PASSED INTO A SYSTEM INITIALLY CONTAINING 90 TO 95% OF FINELY DIVIDED METALLIC OXIDES AND METALLIC SILICATES, INTIMATELY ADMIXED WITH AN ADDITIVE COMPRISING NOT LESS THAN 3% OR MORE THAN 5% WATER, NOT LESS THAN 2% OR MORE THAN 5% DISSOLVED ALKALI HYDROXIDE SUCH AS SODIUM HYDROXIDE OR SODIUM METASILICATE AND BETWEEN 01% TO 0.1% STANNUOUS CHLORIDE OR STANNOUS HYDRIDE ALL OF THE ABOVE NOTED PERCENTAGES BEING BASED ON PARTS BY WEIGHT OF EACH NOTED INGREDIENT PRESENT IN EVERY 100 PARTS BY WEIGHT OF THE SLAG CONTAINING SYSTEM. THE SYSTEM IS STRONGLY AGITATED DURING THE TIME THE WASTE STACK GAS IS BEING PASSED THERETHROUGH. THE SULFUR DIOXIDE CONSTITUENT OF THE STACK GAS IS ENTRAPPED IN THE SLAG SYSTEM AND CAN BE LIBERATED THEREFROM IN ESSENTIALLY PURE FORM BY SUBSEQUENT HEAT TREATMENT OF THE ENTRAPMENT SYSTEM. THE SYSTEM CAN THEREUPON BE RESUED REPEATEDLY FOR ENTRAPMENT OF FURTHER SO2 GAS BECAUSE IT IS ESSENTIALLY REGERATABLE DUE TO THE ADDITION OF THE ADDITIVES NOTED ABOVE WHICH PREVENT UNDUE OXIDATION OF THE COMPONENTS OF THE SYSTEM.

    摘要： An existing riser-reactor into which reactants are injected for reaction therein through a plurality of nozzles is modified to provide the same with additional nozzles and as desired the nozzles are arranged to inject the same or different reactants to portions of the riser-reactor which are separated each from the other so that optimum reaction can take place in each portion. In one form of the apparatus a chamber is constructed around an existing riser-reactor into which at the place surrounded by the chamber there have been inserted and fixed to its wall a plurality of nozzled pipes whereby to feed reactant from the chamber through the pipes and nozzles into the riser-reactor. As desired, the pipes can extend to provide nozzles for injection into the riser-reactor at various depths or levels therein. Also, by partitioning the chamber different reactants can be injected from the overall chamber to different portions of the riserreactors. An apparatus as described can be originally constructed in toto rather than by modifying an existing riser-reactor.

    摘要： A system for effecting the reconditioning of catalyst particles used in the reforming of a hydrocarbon stream which provides a vertically elongated confined chamber that will have the particles flow down between screens of perforated plates in a descending column through a carbon burn-off section and a halogenation section. A preferred design provides for an annularform column of particles with gas flows being out-to-in laterally through the column and, in addition, incorporates a drying section in the lower portion of the chamber. An overall system with a preferred design also combines means for scrubbing the flue gas stream from the burn-off section and returning it to the chamber and, in addition, combines means for continuously recycling a steam-halogen-air stream through the halogenation section.
