DIVIDED SOLID COMPOSITION COMPOSED OF GRAINS PROVIDED WITH CONTINUOUS METAL DEPOSITION, METHOD FOR THE PRODUCTION AND USE THEREOF IN THE FORM OF A CATALYST

摘要

This 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 a homogeneous 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.
