Claims (6)

  1. Procédé pour l'obtention d'arômes purs à partir de reformat,
    au cours duquel procédé, une étape de reformat est obtenue au cours d'une première étape du procédé à partir de reformat par distillation fractionnée avec un aromate d'un nombre de carbone sélectionné Cx ou à l'aide d'aromates de plusieurs nombres de carbone sélectionnés,
    dans lequel l'étape de reformat est hydratée au cours d'une seconde étape du procédé de façon sélective avec du nickel ou du palladium sur un matériau support en tant que catalyseur d'hydratation et par conséquent, les conditions d'hydratation sont réglées de telle sorte que des non-aromates essentiellement soient notamment des oléfines, des dioléfines et des trioléfines, soient hydratées et par conséquent, les dioléfines et les trioléfines conjuguées soient hydratées, si possible, intégralement,
    et au cours duquel procédé ensuite les produits hydratés de façon sélective contenant des aromates sont séparés au cours d'une troisième étape du procédé par distillation d'extraction et / ou par extraction liquide-liquide en des aromates et des non-aromates.
  2. Procédé selon la revendication 1 dans lequel une étape de reformat est obtenue au cours d'une première étape du procédé, laquelle étape contient comme portion aromatique essentiellement du benzène.
  3. Procédé selon l'une quelconque des revendications 1 ou 2 au cours duquel la distillation extractive et / ou l'extraction liquide-liquide est réalisée à l'aide d'un solvant sélectif du groupe N-formylmorphine, N-méthylpyrrolidone, sulfolane, éthylène glycol ou de dérivés d'éthylène glycol.
  4. Procédé selon l'une quelconque des revendications 1 à 3, dans lequel une morpholine N-substituée comprenant 1 à 8 atomes de carbone est utilisée dans des substituants comme solvant sélectif.
  5. Procédé selon l'une quelconque des revendications 1 à 4, dans lequel les alcanes diols comprenant 2 à 5 atomes de carbone et / ou leurs éthers de mono et / ou dialkyle sont utilisés comme solvant sélectif.
  6. Procédé selon l'une quelconque des revendications 1 à 5, dans lequel les aromates purs sont séparés par distillation par le solvant sélectif au terme de la distillation extractive et / ou par extraction liquide-liquide.
