PROCESS FOR PRODUCING CATALYSTS COMPRISING NANOSIZE METAL PARTICLES ON A POROUS SUPPORT, IN PARTICULAR FOR THE GAS-PHASE OXIDATION OF ETHYLENE AND ACETIC ACID TO GIVE VINYL ACETATE

摘要

The invention relates to a method for producing a catalyst containing one orseveral metals from the group of metals comprising thesub-groups Ib and VIIIb of the periodic table on porous support particles,characterised by a first step in which one or several precursorsfrom the group of compounds of metals from sub-groups Ib and VIIIb of theperiodic table is or are applied to a porous support, and asecond step in which the porous, preferably nanoporous support to which atleast one precursor has been applied is treated with at least onereduction agent, to obtain the metal nanoparticles produced in situ in thepores of said support.
