TECHNICAL DESCRIPTION

This invention describes a device to manufacture metallic nanoparticles supported in a fluidized-bed reactor.
The process includes the spraying of an organometallic precursor solution on a fluid bed of inorganic particles as a support, and its further decomposition. The reaction is carried out in mild conditions, the most of the time at room temperature and never higher than 100°C. The solvent evaporates on contact with the particles of the support, which undergoes a better dispersion of the metal inside the pores. The size of the so-obtained supported metal nanoparticles is lower and better controlled and the metal adhesion on the support better than with existing processes.

INDUSTRIAL APPLICATIONS

This method does not involve calcination, and has the advantage of providing a catalyst in only one step. The catalysts obtained using this process are specific, and have high added value. They can be used for heterogeneous catalysis such as hydrogenation, hydroformylation, polymerization and hydrocyanation.
