style="text-indent:25px">鈀碳具有加氫還原性高、選擇性好、性能穩(wěn)定。云南專業(yè)海綿鈀回收</p><p style="text-indent:25px">鈀管純化氫的原理是，在300—500℃下，把待純化的氫通入鈀管的一側(cè)時，氫被化學(xué)吸附在鈀管壁上并解離成氫原子，氫原子與鈀原子形成合金型氫化物，氫原子占據(jù)金屬晶格中的空隙位置，也稱間充型氫化物。在濃度梯度的作用下，氫原子可在鈀管壁中擴(kuò)散，通過鈀管后重新形成氫分子脫附析出，故可利用鈀管獲得高純氫。雖然鈀對氫有獨(dú)特的透過性能，但純鈀的機(jī)械性能差，高溫時易氧化，再結(jié)晶溫度低，易使鈀管變形和脆化，故不能用純鈀作透過膜。在鈀中添加適量的IB族和Ⅷ族元素，制成鈀合金，可改善鈀的機(jī)械性能。應(yīng)用的鈀合金中，銀約占20—30%，其他成分（如金等）的含量<5%。氫透過鈀合金的速率與溫度、膜的厚度及滲透摸兩側(cè)的原料氫和純氫的壓力差（△P）有關(guān)。升高溫度，增大△P及減小膜的厚度，會使透氫速率增加。但溫度升高，將使?jié)B透膜的抗拉強(qiáng)度降低。因此，鈀管的使用溫度通常控制在450℃以下。某些雜質(zhì)可導(dǎo)致鈀中毒，使透氣性能變壞，甚至可使膜遭到破壞。能引起鈀中毒的物質(zhì)有：汞、砷化物、鹵化物、油蒸氣、含硫和含氨物質(zhì)以及粉塵等。云南專業(yè)海綿鈀回收</p><p
