20120016170 | PROCESS FOR PREPARING A CORE-LAYER MATERIAL HAVING GOOD MECHANICAL STRENGTH - A process is described for preparing a spherical material comprising a porous core coated with a continuous and homogeneous porous layer, the degree of attrition of said material being less than 20%. Said preparation process comprises a) bringing a bed of spherical particles constituting the core of said material into contact with a suspension containing an inorganic binder in order to form a solid having a pre-layer around said core; b) bringing the solid derived from step a) into contact, in a stream of hot air, with a powder constituted by spherical particles of an inorganic oxide and a suspension containing an inorganic binder and an organic binder in order to form a solid the core of which is coated with at least one continuous and homogeneous porous layer, the ratio of the (mass of anhydrous inorganic binder/volume of powder particles) being in the range 0.05 to 1 g.mL | 01-19-2012 |
20120149955 | NOVEL PROCESS FOR THE PREPARATION OF PALLADIUM-BASED CATALYSTS AND USE OF SAID CATALYSTS IN SELECTIVE HYDROGENATION - The invention concerns a novel process for the preparation of supported metallic catalysts in which the metallic phase is deposited in the form of agglomerates of nanoparticles of metallic oxide and forms a layer of fine thickness at the surface of the support. The process for the preparation of a catalyst comprises preparing in aqueous phase a colloidal suspension of agglomerates of nanoparticles of metallic oxide, then depositing that suspension on a porous support, drying the catalyst precursor obtained, and optionally calcining and reducing the precursor by means of any reducing compound. The invention also concerns the catalysts obtained by said process and their uses in reactions for the transformation of unsaturated organic compounds. The invention is applied to the refining field and more particularly to the treatment of gasolines obtained by steam cracking and/or obtained by catalytic cracking. | 06-14-2012 |
