The catalysts were tested in the hydrogenation of hexa-1,5-diene in liquid phase, at 313 K. The addition of silver improved the hex-1-ene fractional selectivity in all cases, but lowered the catalyst activity when the Pd/Ag ratio was about unity. On the other hand a palladium-rich (Pd/Ag=4) bimetallic catalyst exhibited a very good activity and a good selectivity to hex-1-ene as well. The effects of silver addition are ascribed to the dilution of palladium atoms by silver atoms, which prevents the isomerisation of hexa-1,5-diene. Hence, the polyol method, which has been used up to now to prepare metal powders with controlled morphology, appears of interest in the elaboration of supported metal catalysts.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2013-01-28T15:19:48Z No. of bitstreams: 1 Sales.pdf: 1268659 bytes, checksum: 338ec80bff1dc0e0f1024ad25bbc5e6f (MD5)Made available in DSpace on 2013-01-28T15:19:48Z (GMT).
