 l'Exploitation des Procédés Edouard URBAIN. 



    @   Pour certains emplois, par-exemple pour l'oenologie, le traitement des huiles ou pour le charbon de protection contre les gaz', les consommateurs exigent soit un charbon en poudre', soit un   charbon .-concasse   suivant une échelle de dimensions bien définie,   Comme',   pour la bonne et régulière fabrication du charbon, il est presque indispensable d'agglomérer la matière ou de la débiter en fragments d'une certaine dimension, on est ensuite obligé de concasser ou de pulvériser le charbon obtenu. 



   L'expérience montre que', par suite de cette opération, l'activité du charbon primitif diminue notablement, 
Les inventeurs ont été conduits', par l'étude qu'ils ont faite de cette diminution d'activité', à l'attribuer en grande partie l'obstruction des pores du charbon par des poussières très fines produites lors   d   broyage et, pour une petite partie, à l'écrasement des oanaux sur la périphérie du grain. 



   Il a été reconnu',. en outre', que cet affaiblissement de l'activité pouvait être pratiquement évité si le broyage avait lieu au sein d'un liquide quelconque:,' de préférence à assez forte tension capillaire. Ce liquide sera,en général', de l'eau, mais on pourra employer aussi', suivant le cas', des huiles ou des   hydrocarbures* Il   

 <Desc/Clms Page number 2> 

 
Si le liquide employé est volatil, on peut sécher le charbon et l'on constate alors qu'il a, après broyage, une 
 EMI2.1 
 activité très voisine de Inactivité primi titre 
Dans certains cas, l'usage du vide pour abaisser la température de séchage est à recommander.   toutefois /   le   séchage   ne s'impose pas et le charbon peut   -,être   livré imbibé du liquide employé';

   en particulier lorsqu'il s'agit d'obtenir un charbon 
 EMI2.2 
 décolorant en Pa - "td-' pour l'oenologie par exemple. 



  REVENDICATIONS. lE'- Procédé pour l'obtention de charbons actifs conoaspé s ou pulvérisés sans perte d9activité',' caractérisé par le fait are le broyage ou la pulvérisation sont effectués au sein d'un liquide quelconque ayant', de préf'érence,' une assez forte ten- sion capillaire' en vue d'éviter l'obstruction des pores du charbon et 3.'é araserAnt des canaux sur la périphérie des grains; 
2 - Procédé suivant 1  caractérisé par le fait que le charbon,' après   l'opération','   reste imbibé du liquide employé ou bien qu'il est lavé et séché.

 the Operation of Edouard URBAIN Processes.



    @ For certain uses, for example for oenology, the treatment of oils or for gas protection charcoal, consumers demand either powdered charcoal or crushed charcoal according to a scale of dimensions well defined, As', for the good and regular production of coal, it is almost essential to agglomerate the material or to cut it into fragments of a certain size, one is then obliged to crush or pulverize the coal obtained.



   Experience shows that ', as a result of this operation, the activity of the original coal significantly decreases,
The inventors were led ', by the study they made of this decrease in activity', to attribute it largely to the obstruction of the pores of the carbon by very fine dust produced during grinding and, for a small part, to the crushing of the channels on the periphery of the grain.



   He was recognized ',. moreover, that this weakening of the activity could be practically avoided if the grinding took place in any liquid:, preferably at fairly high capillary tension. This liquid will generally be 'water, but we can also use', as the case may be ', oils or hydrocarbons *

 <Desc / Clms Page number 2>

 
If the liquid used is volatile, the charcoal can be dried and it is then observed that, after crushing, it has a
 EMI2.1
 activity very similar to Inactivity first title
In some cases, the use of vacuum to lower the drying temperature is recommended. however / drying is not necessary and the charcoal can - be delivered soaked in the liquid used ';

   in particular when it comes to obtaining a coal
 EMI2.2
 decolorizer in Pa - "td-" for wine, for example.



  CLAIMS. The process for obtaining activated charcoal s or pulverized without loss of activity ',' characterized by the fact that the grinding or pulverization are carried out in any liquid having ', preferably,' a strong enough capillary tension to avoid clogging of the charcoal pores and to level the channels on the periphery of the grains;
2 - Process according to 1 characterized in that the charcoal, 'after the operation', 'remains soaked in the liquid used or else it is washed and dried.
