稀土觸媒材料

稀土助催化材料

由於稀土元素具有特殊的外層電子結構 (4f),其作為絡合的中心原子,具有從6-12的各種配位數。稀土元素這種配位數的可變性,決定了它們具有「剩餘的原子價」。因為4f有7個後備電子軌道具有成鍵能力,起著某種「後備化學鍵」或「剩餘原子價」的作用,這種能力正是催化劑所必須具備的。因此稀土元素不僅本身具有催化活性,還可以作為添加劑或助催化劑,以提高催化劑的催化性能,尤其是抗老能力和抗中毒能力。稀土催化材料包括分子篩稀土催化材料、稀土鈣鈦礦催化材料、鈰鋯固溶體催化材料等,可用於內燃機尾氣催化淨化,工廠廢氣及人居環境淨化、催化燃燒、燃料電池、低值烷烴利用等。

Rare earth oxygen storage materials have many advantages such as excellent oxygen storage capacity, faster oxygen storing/releasing rate, lower firing point and higher hermal resistance stability. It also can promote the dispersing of precious metals, reducing the quantity of the precious metal, improving the catalytic activity and extending life time of the catalyst. This product can be applied in many areas, including automobile and motorcycle exhaust gas purification, catalytic combustion, industrial waste gas treatment, etc.

Dedicated to gasoline vehicles and their three-way catalytic converters, rare earth catalyst materials are present in catalytic converters worldwide today. Our product range reduces usage of precious metals whilst simultaneously improving catalytic converter performance and durability

 

鈰鋯基固溶體具有優異的儲、放氧功能,是三效催化劑(TWC)的重要組成分之一,其在催化反應過程中既起到調節空燃比的作用,同時作為催化劑載體,有效提高了貴金屬催化劑的催化活性和抗燒結性,可顯著提高汽車尾氣和工廠廢氣中碳氫化合物(HC)、一氧化碳(CO)、和氮氧化物(NOx)等有害氣體的話淨化效率。

稀土-鋯複合載體塗層材料具有比表面積穩定,顆粒均勻等特點,可用於機動車尾氣淨化、天然氣催化燃燒、工廠廢氣處理、室內空氣淨化、以及煉油工廠中的流畫催化裂解。使用稀土-鋯複合載體塗層材料可在不降低淨化效過的同時,減少貴金屬用量,顯著降低了催化淨化器在製造企業的生產成本。

 

Coating material with RE-zirconium composite carrier has a perfect surface area stability, particles uniformity and other characteristics. It can be used in purification catalyst of vehicle exhaust gas, catalytic combustion of natural gas, the treatment of industrial waste gas, the purification of indoor air, as well as the oil refining industry in Sulfide catalytic cracking. RE-zirconium composite carrier coating materials can reduce the dosage without damaging purification effect, at the same time, significantly reducing relative enterprise costs.

 

 

稀土-鋯複合載體塗層材料具有以下特點:

  1. 組成配分科學合理:以氧化鈰和氧化鋯固然體為基體,摻雜了部分氧化鑭和氧化釔,使產品具有最佳的儲氧量和穩定的比表面積。
  2. 老化比表面積穩定:通過控制孔隙率和孔徑,使塗層材料的比表面積大且穩定,增加了催化氣的耐久性能。
  3. 顆粒細且分布均勻:採用研磨和精密分級技術,使材料再塗覆過程中不沉降,提高產品的一致性。
