Definitions

  • the first coal showed a softening behavior between 330 and 400 ° C, the softening temperature differences of the second coal were 370 and 430 ° C.
  • the swelling index was for the first coal 2 1/2 and for the second coal 2.
  • the first coal having the lower temperature location mm was ground to grain sizes below 0.1, wherein the percentage of particles below 0.06 mm at 63 wt. -% was.
  • the coal with the higher softening temperature had a grain size of 0.3 to 3 mm.
  • the two types of coal were mixed in a weight ratio of 3: and briquettes were produced from the mixture as in Example 2. After the treatment described in Example 1, the advantageous results already found there also resulted.

6. Procédé suivant la revendication 1 ou l'une des suivantes caractérisé en ce qu'on ajoute des liants organiques ou inorganiques au charbon du mélange, particulièrement de la poix, du goudron, du coke de craquage, des résidus d'hydrogénation, de la chaux, de la bentonite, de la mélasse, de la dolomie, de la montmorillonite ou de lessive résiduaire de sulfite.
7. Procédé suivant la revendication 1 ou l'une des suivantes caractérisé en ce qu'on ajoute des substances catalytiques aux charbons du mélange, particulièrement de NaCI, du KCI, du Na2C03, du K2CO3, des oxydes du molybdène, du tungstène, de l'étain, du chrome, du nickel, du cobalt ou du fer, ou des zéolithes finement moulues.
8. Procédé suivant la revendication 1 ou l'une des suivantes caractérisé en ce qu'on ajoute aux charbons du mélange des substances qui diminuent les propriétés de prise en masse et de gonflement des charbons, particulièrement du Na2B4O7, du NaN02, du K2CrO4, du K2CO3 ou du KN03.
9. Procédé suivant la revendication 1 ou l'une des suivantes caractérisé en ce qu'on sèche les corps moulés avant de les soumettre à la gazéification.
