CA 2570590
The invention relates to a solid divided composition comprising grains whose mean size is greater than 25µm and less than 2.5 mm, wherein each grain is provided with a solid porous core and homogenous continuous metal layer consisting of at least one type of transition non-oxidised metal and extending along a gangue coating the core in such a way that pores are inaccessible. A method for the production of said composition and for the use thereof in the form of a solid catalyst is also disclosed.
L'invention concerne une composition solide divisée comprenant des grains de granulométrie moyenne supérieure à 25 ~m et inférieure à 2,5 mm, et présentant chacun un cAEur solide poreux et une couche métallique continue homogène formée d'au moins un métal de transition non oxydé et s'étendant selon une gangue couvrant le cAEur en rendant les pores inaccessibles. Elle s'étend au procédé de fabrication d'une telle composition, et à son utilisation à titre de catalyseur solide.
