  Procédé pour la régénération des matières ayant     servi    à l'épuration du gaz d'éclai  rage avec     récupératlon    simultanée de leur soufre sous forme d'an     mélange        concentré     de     polysulfures    de calcium ferrugineux.    On sait que les matières ayant servi  l'épuration du gaz d'éclairage ont perdu leur  pouvoir absorbant, dès que leur oxyde de fer  a absorbé environ 50 % de soufre.  



  L'objet de la présente invention est un  procédé pour la régénération de     ces        matières     ayant servi à l'épuration du gaz d'éclairage,  avec récupération simultanée de leur soufre  sous forme d'un mélange concentrée de poly  sulfures de calcium ferrugineux, c'est-à-dire,  contenant du fer en solution, susceptible  d'être employé clans l'agriculture, dans la  zoothérapie et dans l'hydrothérapie.  



  Suivant ce procédé, on ajoute les matières  ayant servi à l'épuration. du gaz dans de  l'eau dans laquelle -on a préalablement éteint,  de la chaux, fait bouillir la masse en résul  tant et sépare par décantation les matières  non dissoutes, qui renferment les matières  d'épuration     régénérées,        chi    liquide qu'on  soumet, après filtration, à une concentration  dans le vide.

  Process for the regeneration of the materials used for the purification of the lighting gas with simultaneous recovery of their sulfur in the form of a concentrated mixture of ferruginous calcium polysulphides. It is known that the materials used to purify the lighting gas have lost their absorbing power as soon as their iron oxide has absorbed about 50% of sulfur.



  The object of the present invention is a process for the regeneration of these materials having been used for the purification of the lighting gas, with simultaneous recovery of their sulfur in the form of a concentrated mixture of ferruginous calcium poly sulfides, that is, that is to say, containing iron in solution, capable of being used in agriculture, in zootherapy and in hydrotherapy.



  According to this process, the materials used for the purification are added. gas in water in which lime has been extinguished beforehand, the resulting mass boils and separates by decantation the undissolved materials, which contain the regenerated purification materials, chi liquid which is subjected , after filtration, to a concentration in vacuum.
