The invention relates to methods and devices for regenerating activated carbon mainly used in air-treating devices of means of transport, in particular for the passenger compartment thereof. The invention also can be used for regenerating activated carbon for air-treating devices in other areas. The inventive method for regeneration of activated carbon mainly used for air treating purposes in the passenger compartment of the means of transport consists in a regeneration which is performed with the aid of the water vapor obtained from condensates of humidity in the atmosphere. Said condensates are pre-absorbed during air treatment with the aid of silica gel. The regeneration is carried out with an atmospheric pressure at a temperature of up to 160 °C followed by cooling carried out with the aid of a fan having an air flow of not less than 25 min-1. The inventive device for regenerating the activated carbon with the aid of water vapor comprises a sorption cartridge and a silica gel and activated carbon placed therein, a heating element for heating the sorption cartridge during the regenerating process and the fan connected to the sorption cartridge for cooling said cartridge and emitting regeneration products in to the atmosphere.

Zur Desorption eines mit Schadstoffen beladenen körnigen kohlenstoffhaltigen Adsorptionsmittels. Hierzu wird vorgesehen, daß dem beladenen Adsorptionsmittel ein sauerstoffhaltiges Oxidationsgas zugeführt wird derart, das es durch Teiloxidation auf die Desorptionstemperatur erhitzt wird. Die Zufuhr von Sauerstoff wird so gesteuert, daß ein Verbrennen des Adsorptionsmittels nicht möglich ist. Das erfindungsgemäße Verfahren eignet sich insbesondere für die Regeneration von in Rauchgasentschwefelungsanlagen benutztem Aktivkoks.

摘要:
The present invention relates to an apparatus and a method for the regeneration of the granular activated carbon, preferably with grain sizes of between 1 mm and 10 mm, contained in the activated carbon filters used inside an industrial plant. The method and the apparatus that allows its implementation allow the continuous regeneration of the activated carbon contained in the moving-bed or fixed-bed filters of an industrial plant without requiring a plant shutdown, without having to disassemble the filters, and without having to replace the exhausted activated carbon with new activated carbon except after a large number of regenerations of the entire carbon, thus allowing considerable efficiency of operations and an extremely low environmental impact.
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 DEG F (482 DEG 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.
