The invention pertains to a method of passivating direct process solids (1) and to passivated and quenched compositions resulting from said method. The method of passivating direct process solids (1) according to the invention comprises combining direct process solids (1) with a passivating composition comprising clay (2), base (3), and water (4). The passivated composition of the invention comprises direct process solids (1) and a passivating composition comprising clay (2), base (3), and water (4). The quenched composition of the invention comprises the passivated composition, wherein the passivated composition has been held for a sufficient period of time for the reactive species from the direct process solids to be substantially quenched and/or oxidized.
L'invention concerne un procédé de passivation de matières solides dites par processus direct, et des compositions passivées et désactivées issues d'un tel procédé. Le procédé selon l'invention de passivation de matières solides dites par processus direct consiste à combiner les matières solides ainsi désignées avec une composition de passivation qui contient de l'argile, une base et de l'eau. La composition passivée selon l'invention comprend les matières solides considérées et une composition de passivation qui renferme de l'argile, une basse et de l'eau. La composition désactivée selon l'invention renferme la composition passivée, laquelle a été maintenue pendant une durée suffisante pour que l'espèce réactive des matières solides considérées soit sensiblement désactivée et/ou oxydée.
