Description

  

  Procédé de traitement de la tourbe en vue de l'obtention simultanée d'hydrates  de carbone solubles non destinés à l'alimentation et d'un produit     combustible.       .Le présent procédé est basé sur la cons  tatation que la tourbe     à,6,5-85    % d'eau, trai  tée à chaud par les acides, peut être facile  ment, par exemple par essorage ou par fil  tration sous pression, débarrassée de la ma  jeure partie du liquide aqueux qui l'im  prègne, au contraire de ce -qui se passe pour  la tourbe non traitée. Cette propriété, due à  la transformation en cours d'opération des  produits colloïdes contenus dans la tourbe,  permet aussi un lavage méthodique facile de  la tourbe traitée.  



  Selon ce procédé, de la tourbe contenant  65-85 % d'eau et 15-35 % de matière sèche  est additionnée par pulvérisation, dans un ma  laxeur, d'acide sulfurique concentré, par  exemple en quantité suffisante pour que la  concentration du liquide imprégnant la tourbe  soit d'environ 4 % .d'acide pur. La masse ainsi  préparée est chauffée sous pression à  110  -120   pendant un laps de temps qui  dépend de l'origine de la tourbe. On sépare  ensuite de la masse, de préférence encore  chaude et par essorage ou par compression,  la partie liquide, puis on lave méthodique-    ment la partie solide. Les liquides sont trai  tés ensuite pour la     mise    en valeur des hy  drates de carbone qu'ils renferment.

   Après  le -dernier lavage, la masse est comprimée en       briquettes    avec ou sans     addition    d'un agglo  mérant.  



  Ce procédé peut être exécuté de façon à  réaliser les trois conditions suivantes, néces  saires pour assurer une     application    écono  mique du     traitement    de la tourbe pour l'ob  tention des hydrates de carbone solubles:  <B>10</B> Obtention de solutions, d'hydrates de  carbone suffisamment     concentrées    de façon à  éviter des frais d'évaporation trop considé  rables si l'on veut obtenir des hydrates de  carbone solides ou des frais de concentration  des solutions fermentées, si l'on transforme  ces hydrates de carbone par fermentation.  



  20 Emploi d'une quantité d'acide suffi  samment faible par rapport aux hydrates de  carbone produits, de façon à réduire les dé,  penses d'acide.  



  <B>30</B> Obtention du résidu du traitement à  l'acide sous forme d'un combustible de plus  de valeur que la tourbe elle-même, .de façon à      ajouter le bénéfice -de la vente de ce produit  ' à celui des hydrates de carbone.



  Process for the treatment of peat with a view to obtaining simultaneously soluble carbohydrates not intended for food and a combustible product. The present process is based on the finding that the 6.5-85% water peat moss, hot treated with acids, can be easily, for example by dewatering or by pressurized filtration, freed. most of the aqueous liquid which pervades it, unlike untreated peat. This property, due to the transformation during operation of the colloid products contained in the peat, also allows easy methodical washing of the treated peat.



  According to this process, peat containing 65-85% water and 15-35% dry matter is added by spraying, in a laxor, concentrated sulfuric acid, for example in sufficient quantity so that the concentration of the liquid impregnating the peat is about 4% pure acid. The mass thus prepared is heated under pressure at 110 -120 for a period of time which depends on the origin of the peat. The liquid part is then separated from the mass, preferably still hot and by suction or by compression, and the solid part is then washed methodically. The liquids are then treated for the enhancement of the carbohydrates they contain.

   After the last washing, the mass is compressed into briquettes with or without the addition of an agglomeration.



  This process can be carried out in such a way as to achieve the following three conditions, necessary to ensure an economical application of the treatment of peat for obtaining soluble carbohydrates: <B> 10 </B> Obtaining solutions, sufficiently concentrated carbohydrates so as to avoid excessive evaporation costs if one wishes to obtain solid carbohydrates or costs of concentration of fermented solutions, if these carbohydrates are transformed by fermentation .



  Use of an amount of acid which is sufficiently low relative to the carbohydrates produced, so as to reduce the acid expenditure.



  <B> 30 </B> Obtaining the residue of the acid treatment in the form of a fuel of more value than the peat itself, so as to add the benefit of the sale of this product to that of carbohydrates.
