摘要： Improved method and apparatus are disclosed for regenerating wet spent carbon containing volatile impurities wherein the wet spent carbon is dried in a drying zone utilizing incinerated reactivation zone gaseous effluent. The improvement of the invention provides that the portion of reactivation zone gaseous effluent used to dry the wet spent carbon in the drying zone is continuously recycled to the reactivation zone for incineration to remove any volatile impurities which may have been removed from the wet spent carbon during drying. The balance of the reactivation zone gaseous effluent may be discharged into the atmosphere without further incineration.

摘要： A method of removing water from activated carbon is disclosed. Briefly, the method comprises (a) passing liquid 1,2-dichloroethane through a bed of activated carbon until a bulk water phase ceases to exit the bed or until from about 60 to about 80 weight percent of the water present in a water-saturated bed has been removed and (b) removing substantially all of the remainder of the water present by use of vacuum or by passing hot air or hot nitrogen through the activated carbon.

摘要： Method and apparatus are disclosed for regenerating wet spent carbon containing volatile impurities wherein the wet spent carbon is dried in a drying zone utilizing incinerated reactivation zone gaseous effluent. The reactivation zone gaseous effluent is derived by reactivating dried spent carbon in a reactivation zone at pyrolysis conditions to remove volatile components from the adsorbent. Removal is effected utilizing combustion gases. The reactivation zone gaseous effluent is comprised of the combustion gases, the vaporized volatile impurities, and, where steam is employed in the reactivation zone to remove fixed carbon, substantial quantities of carbon monoxide and hydrogen. By interposing the incineration zone between the drying and reactivation zone, efficiency of the overall process is maximized. The combustible components of the combustion gases, the volatile impurities and the carbon monoxide and hydrogen, produced by removal of fixed carbon with steam, are burned in such a manner that the heat of combustion is used for drying the incoming wet spent carbon and for maintaining pyrolysis conditions required for reactivation. The effluent gases may be discharged directly into the atmosphere without further incineration.
摘要翻译：公开了用于再生含有挥发性杂质的湿废碳的方法和装置，其中使用焚烧的再活化区气态流出物在干燥区中干燥湿废碳。再活化区气态流出物是通过在热解条件下在再活化区中再次干燥的废碳以从吸附剂中除去挥发性组分得到的。使用燃烧气体进行去除。再活化区气体流出物由燃烧气体，蒸发的挥发性杂质组成，并且在再活化区中使用蒸汽以除去固定碳，大量一氧化碳和氢气的情况下。通过将焚烧区置于干燥和再生区之间，整个过程的效率最大化。通过用蒸汽去除固定碳产生的燃烧气体的可燃组分，挥发性杂质和一氧化碳和氢气被燃烧，使得燃烧热用于干燥进入的湿废碳并维持重新激活所需的热解条件。废气可以直接排放到大气中而不进一步焚烧。

摘要： Process for regenerating activated carbon particles contaminated by oxidizable impurities. An electrolysis cell is divided by a liquid-permeable membrane to define an anodic chamber and a cathode chamber therein both filled in operation with an electrolyte. Recycling conduits communicate with the anode chamber and a recirculating pump to establish a fluid circuit therewith. A suspension of particles of activated carbon contaminated by oxidizable impurities suspended in an aqueous solution of an electrolyte is loaded into the fluid circuit and circulated therethrough. A voltage applied to the electrodes of the electrolysis cell develops an electrolysis reaction in the aqueous solution of the electrolyte and atomic oxygen is liberated at the surface of the anode electrode. As particles of the activated carbon flow through the anode cell they contact the anode electrode and atomic oxygen is liberated at their surfaces which oxidizes impurities adsorbed by the particles. After the carbon particles have been circulated for a sufficient time to oxidize all of the impurities thereon, the regenerated particles of activated carbon and the aqueous solution of the electrolyte are discharged from the recirculating circuit.

摘要： An adsorbate is removed from an adsorbent by contacting the adsorbent with a near critical liquid which is a solvent for the adsorbate. The near critical liquid containing the dissolved adsorbate is then subjected to at least partial vaporization to form a vapor in which the adsorbate is substantially less soluble thereby making it possible to remove the adsorbate from the near critical liquid. The vapor is then condensed to restore it to the near critical liquid state wherein it is a solvent for the adsorbate so that it may be reused. The process is particularly suitable for adsorbent regeneration in the treating of waste-waters.

摘要： An adsorbate is removed from a polymeric adsorbent by contacting the adsorbent with a supercritical fluid which is a solvent for the adsorbate. The supercritical fluid containing the dissolved adsorbate is then subjected to a physical treatment which renders the supercritical fluid a nonsolvent for the adsorbate and makes it possible to remove the adsorbate from the supercritical fluid. The supercritical fluid is then subjected to another physical treatment to restore it to a state wherein it is a solvent for the adsorbate so that it may be reused. The process is particularly suitable for adsorbent regeneration in the treatment of wastewaters.

摘要： A liquid is contacted with an adsorption agent so that the latter adsorbs and retains the impurities in the liquid. Subsequently, a portion of the purified liquid is vaporized. The vapor is brought into contact with the adsorption agent and removes the adsorbed impurities therefrom to thereby regenerate the adsorption agent. After condensation of the vapor so as to segregate the impurities removed from the adsorption agent, the resulting liquid may again be contacted with the adsorption agent.

摘要： Aqueous solutions and suspensions of solid particles, even those containing less than one percent of organic materials, may be combusted with air, oxygen, or their mixtures in a process which provides for preheating in countercurrent batches of the raw original liquid by either open (direct contact) or closed (heat transfer surface) condensation of steam generated by multiple flash evaporations which cool earlier batches of hot liquid after the wet combustion. Excess heat may often be withdrawn from the process for power generation or other use as high pressure steam, with or without combustion gases and other non-condensibles. No pumps are necessary, liquid batches are pressurized by steam generated in the flash evaporations for which only one pressure vessel is required instead of the many in the continuous processes.Waste liquids as sewage sludges and black liquors from wood pulping may have their organic constituents, as measured by BOD or COD, so reduced that the final, spent liquid may be discharged directly to a receiving body of water.

摘要： Solvent regeneration of activated carbon on which a chemical species is sorbed is enhanced by the selective use of a regenerant solution containing a solvent for said chemical species and a predetermined concentration of the chemical species in solution. The stream of spent regenerant coming from the carbon is thereby made more concentrated in solute and easier to treat for separation of the solute and solvent.

摘要： Contaminated adsorbent particles, preferably activated carbon particles, are regenerated in water at supercritical conditions. The particles are preferably mixed in water prior to treatment. The mixture is preferably heated to a temperature at least about 900.degree. F. (482.degree. C.) and pressurized to a pressure sufficient to achieve supercritical conditions for water. The mixture is preferably flowed through a first reactor for a time sufficient to substantially remove the organic contaminants from the particles. The particles are separated from the water and the mixture of water and organic contaminants may be transferred to a second reactor. Within the second reactor the organic contaminants are preferably substantially oxidized by supercritical water oxidation.
