摘要： A method for uniformly dispersing noble metal particles on a porous carrier by first mixing an alkoxide product of aluminum or silicon and a noble metal precursor together; then mixing a surfactant into the mixture; then mixing ammonia solution into the mixture to form a hydroxide of aluminum or silicon; then mixing a reducing agent into the mixture to convert the noble metal precursor into noble metal nanoparticles dispersed on the hydroxide; then separating the noble metal nanoparticles and the hydroxide from the mixture before calcining the hydroxide into an oxide of aluminum or silicon.

摘要： The present invention provides a method of making a noble metal catalyst, where the noble metal is distributed on the surface of special composite carrier particles. Nanometer sized oxide particles are first dry coated by an impact mixing process on the surface of larger alumina particles. In general, this dry coating process coats the nanometer sized particles on the surface of the alumina particles. A suitable solution of noble metal(s) compound is then soaked on the surface of the composite carrier particles. Ultimately, the noble metal compound is decomposed by calcining and noble' metal particles dispersed with large effective surface area on the composite carrier particles. The resultant catalyst structure improves catalyst performance while making efficient and effective use of the expensive noble metal.
摘要翻译：本发明提供了一种制备贵金属催化剂的方法，其中贵金属分布在特定复合载体颗粒的表面上。纳米尺寸的氧化物颗粒首先通过冲击混合工艺在较大的氧化铝颗粒的表面上进行干燥涂覆。通常，这种干式涂覆工艺将纳米尺寸的颗粒涂覆在氧化铝颗粒的表面上。然后将贵金属化合物的合适溶液浸泡在复合载体颗粒的表面上。最终，贵金属化合物通过煅烧和分散在复合载体颗粒上的具有大有效表面积的贵金属颗粒分解。所得到的催化剂结构提高了催化剂的性能，同时有效地使用昂贵的贵金属。
