Abstract
(EN)
The present invention relates to a raw material composition for manufacturing oxygen transfer particles, the raw material composition comprising: copper oxide; manganese oxide; magnesium oxide or magnesium hydroxide; and sol- or powder-type alumina oxide. The raw material composition for manufacturing oxygen transfer particles of the present invention is manufactured into oxygen transfer particles by controlling the composition, the formulation of raw materials, and the homogenizing degree according to the manufacturing method for oxygen transfer particles, to be later described, and thereafter, oxygen transfer particles can be manufactured that have physical properties, such as a shape, a particle size, and a size distribution, which are suitable for a fluidized bed or high-rate fluidized bed process, and retain commercial-grade oxygen transfer performance and durability at a low burning temperature while not using a high-priced nickel-based oxide as in the prior art.

La présente invention concerne une composition de matière première pour la fabrication de particules de transfert d'oxygène, la composition de matière première comprenant : de l'oxyde de cuivre ; de l'oxyde de manganèse ; de l'oxyde de magnésium ou de l'hydroxyde de magnésium ; et de l'oxyde d'alumine de type sol ou poudre. La composition de matière première pour fabriquer des particules de transfert d'oxygène de la présente invention est transformée en particules de transfert d'oxygène par contrôle de la composition, de la formulation de matières premières, et du degré d'homogénéisation selon la méthode de fabrication de particules de transfert d'oxygène, ultérieurement décrite, et par la suite, des particules de transfert d'oxygène peuvent être fabriquées qui ont des propriétés physiques, telles qu'une forme, une taille de particule et une distribution de taille, qui sont appropriées pour un procédé à lit fluidisé ou à lit fluidisé à haut débit, et conservent des performances de transfert d'oxygène de qualité commerciale et une durabilité à une basse température de combustion tout en ne faisant pas appel à un oxyde à base de nickel à prix élevé comme dans l'état actuel de la technique.
