Abstract

Process for preparing catalysts, characterized in that it comprises the steps of: (I) inducing a substantially atomic dispersion of catalytic material on the surface of particles that are compatible with the material for bonding on the surfaces of the particles, without agglomeration, a major proportion of the atoms of the material that impinge on them, to thereby provide a coating of catalytic material; and (II) associating the particles, treated as in step (I), with support material for the catalytic material, where the support material is compatible with the treated particles, to adhere the treated particles and the support material together .
