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。上海海綿鈀公司鈀碳回收后對廢鈀催化劑中的貴金屬鈀進(jìn)行提取具有非常高的經(jīng)濟(jì)價值。</p><div

style="text-indent:25px">鈀碳是一種黑色粉末狀顆粒的化學(xué)物質(zhì)。是一種催化劑，主要作用是對不飽和烴或CO的催化氫化。本身具有多種特點，廣泛應(yīng)用于多個行業(yè)。原裝鈀碳的有效物質(zhì)含量為0.5%、5%、10%。鈀碳可以回收和提純，鈀碳回收提純對鈀金的損耗基本沒有，廢鈀碳的價錢也是不確定的，主要是看鈀的含量，含量越高價格也越高。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，制成鈀合金，可改善鈀的機(jī)械性能。鈀金的外觀與鉑金相似，呈銀白色金屬光澤，色澤鮮明。含鈀等貴金屬的廢料一般都是需要進(jìn)行回收再次利用的。</p><div

鉑金即白金。是一種非常珍貴的貴金屬，與金、銀相比，它用于首飾制造的時間較晚。由于鉑具有艷麗的白色，優(yōu)異的延展性以及耐磨、耐酸性，從19世紀(jì)開始，它就開始廣泛應(yīng)用于首飾制造中。鉑類金屬在地殼中的自然儲量為8萬噸，可開采儲量7.1萬噸，其中，鉑占50%，鈀占35%，釕占9%，銠占6%。2004年，世界鉑類金屬開采量為467噸，世界鉑的開采量為214噸，其中南非開采鉑160噸，俄羅斯36噸，加拿大7噸，美國4噸;2004年，世界銠的開采量為188噸，其中南非開采78.5噸，俄羅斯74噸，美國13.7噸，加拿大12噸。
