style="text-indent:25px">德誠小編帶您了解鈀炭催化劑的稀有性和回收再利用重要性，鈀金在應(yīng)用、收藏以及儲備方面愈發(fā)被重視，金屬鈀屬于稀有貴金屬，在自然界中的儲藏量很少。鈀碳催化劑是非常重要的化工原料，我們國家對鈀的儲藏量及開采量有一定限度。廢鈀催化劑為鈀寶貴的二次資源，有相當高的回收價值。根據(jù)我國發(fā)展現(xiàn)狀和前景的預(yù)測，在石化工業(yè)、聚酯工業(yè)、汽車環(huán)保等領(lǐng)域開展鈀催化劑的回收生產(chǎn)將產(chǎn)生巨大的經(jīng)濟效益。特別是在石油重質(zhì)化提高和Pd資源趨緊價格上揚，加強廢催化劑回收的研究并將成果盡快用于工業(yè)化生產(chǎn)是一項極為緊迫的任務(wù)。</p><p style="text-indent:25px">鈀合金可制成膜片(稱鈀膜)。鈀膜的厚度通常為0.1mm左右。主要于氫氣與雜質(zhì)的分離。鈀膜純化氫的原理是，在300—500℃下，把待純化的氫通入鈀膜的一側(cè)時，氫被吸附在鈀膜壁上，由于鈀的4d電子層缺少兩個電子，它能與氫生成不穩(wěn)定的化學(xué)鍵(鈀與氫的這種反應(yīng)是可逆的)，在鈀的作用下，氫被電離為質(zhì)子其半徑為1.5×1015m，而鈀的晶格常數(shù)為3.88×10-10m(20℃時)，故可通過鈀膜，在鈀的作用下質(zhì)子又與電子結(jié)合并重新形成氫分子，從鈀膜的另一側(cè)逸出。在鈀膜表面，未被離解的氣體是不能透過的，故可利用鈀膜獲得高純氫。雖然鈀對氫有獨特的透過性能，但純鈀的機械性能差，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，可改善鈀的機械性能。鈀的沉淀率隨著硝酸濃度的增加而降低。</p><div

隨著環(huán)境保護日益重要，催化劑的深入開發(fā)和應(yīng)用，對金屬鈀的需求迅猛增長。而鈀碳回收技術(shù)越來越完善，目前對鈀含量低的鈀合金中的鈀回收主要工藝方法是先將廢鈀合金用王水或硝酸溶解，然后進行趕硝、轉(zhuǎn)化等傳統(tǒng)化學(xué)方法回收，后再用黃藥富集回收。但是這種方法對鈀含量小于20%的合金回收成本太高，首先是試劑消耗量大，尾液多不環(huán)保，鈀直收率和回收率均較低。廢料是銀銅鈀合金，其中貴金屬鈀含量是5%，銀的含量68%，銅的含量27%。需要的試劑有硝酸、鹽酸、氨水、水合肼等。
