procédé pour augmenter le pouvoir décolorant du charbon décolorant.
On a déjà publié dans le cours des temps,un grand nombre de procédés très divers pour la préparation de charbons actifs ou charbons décolorants. Les chaubrns obténus diaprés ces procédés présentent une énergie d'absorption très différente vis à vis des matières colorantes.Leur valeur est par suite extrêmement différente,et elle varie entre des limites très étendues. jusqu'il ici on ne-connaissait aucun moyen pour augmenter ultérieurement l'énergie décolorante des charbons une fois préparés.
Or on a réus, si maintenant de façon simple, à augmenter le pouvoir décolorant de ces charbons actifs ou charbons décolorants, après avoir recon nu,à l'examen de divers produits du commerce, que le pouvoir déco- lorant 'des différentes sortes de charbon est généralement fonc- tion de la' grandeur de leurs particules.
En pulvérisant longuement un charbon décolorant quelconque du commerce,en particulier par le broyage par exemple, sur un train de moules ou dans un broyeur a boulets, ou tout autre dispositif analogue, on peut augmenter considérablement
<Desc/Clms Page number 2>
l'énergie décolorante du charbon en .question,ce qui augmente sa valeur commerciale .'Par le 'broyagehumide de charbon de hêtre ordinaire par exemple,- charbon qui, à l'état où il'se rencontre généralement dans le commerce, ne possède qu'unefaible proprié- té décolorante, on a pu décupler son pouvoir décolorant,tandis que par le broyage humide un' charbon décolorant de haute valeur a augmenté encore de 150/un.autre.d'environ,
300 % . Dans la plupart des cas un broyage humide de 10 à 20 heures suffit pour obtenir le maximum d'effet. Le charbondélayé dans l'eau peut être débarrassé de cette eau de façon usuelle par filtrage,pres- surage ou essorage, et le charbon humide peut être séché suivant les besoins pour enlever toute l'eau.

process for increasing the bleaching power of bleaching charcoal.
A large number of very diverse processes for the preparation of activated charcoals or bleaching charcoals have already been published in the course of time. The chaubrns obtained in these processes have a very different absorption energy with respect to the coloring matters, their value is therefore extremely different, and it varies between very wide limits. heretofore no means were known to subsequently increase the bleaching energy of the coals once prepared.
Now we have succeeded, so now simply, in increasing the decolorizing power of these activated charcoals or decolorizing carbons, after having recognized, on examination of various commercial products, that the decolorizing power of the different kinds of charcoal is generally a function of the size of their particles.
By spraying for a long time any decolourising charcoal of any trade, in particular by grinding, for example, on a train of molds or in a ball mill, or any other similar device, one can considerably increase
<Desc / Clms Page number 2>
the bleaching energy of the coal in question, which increases its commercial value. By the wet grinding of ordinary beech coal, for example, - coal which, in the state in which it is generally found in commerce, does not possess A low bleaching property, its bleaching power could be increased tenfold, while by wet grinding a high-value bleaching charcoal further increased by about 150 µm.
300%. In most cases, wet grinding for 10 to 20 hours is sufficient to obtain the maximum effect. The water washed charcoal can be freed from this water in the usual way by filtering, pressing or squeezing, and the wet charcoal can be dried as needed to remove all the water.
EMI2.1
R E V E N D I C A T I 0 N.
Process for increasing the bleaching power of active charcoal or bleaching charcoal, characterized in that bleaching charcoal of any origin is subjected to a grinding operation, preferably to prolonged wet grinding in a grinder of any construction, for example on a train of grinding wheels, in a ball mill or similar device.
