Pd / C Catalyst Used In The Gas Phase Hydrogenation Of Benzene

A Study of preparation methodes , prepara— tion factors of Pd/C catalysts and how these factors affected the activity , dispersionand the size of surface palladium particles had been made in this dissertation .Experiment results had shown that the stability and the ability of anti—poisoning of ion—exchanged type Pd/C catalysts were much better than that of impregneted type pd/C catalysts . All of these catalyst had been carefully characterized by hy rogen—oxygen titration , SEM, AES and etc . Mea while , the activity of ben— (?)ene hydrogenation on these catalysts had also been investigated .Being used a steady— state flow integral reactor with fixed cata— lysts at the atmosphere pressure , the applying circumstances of Pd/C catalysts had been studied at the same time , too...
