Ln2O3/ZrO2催化合成DOP、DOM和DOA
Catalytic Synthesis of DOP,DOM and DOA with Ln2O3/ZrO2 Catalyst
【摘要】 采用共沉淀 -焙烧法制成的Ln2 O3 /ZrO2 (Ln =Nd、Sm、Er)担载型催化剂 ,由于比表面增大 ,分散性好 ,在催化合成DOP、DOM和DOA中效果明显 ,且Ln2 O3 的用量比用纯Ln2 O3 催化剂下降 60 %左右。
【Abstract】 The catalytic synthesis of DOP,DOM and DOA with catalyst Ln 2O 3/ZrO 2 (Ln=Nd,Sm,Er),prepared by coprecipitation-calcination method,has resulted in distinct efficiency improvement and due to its larger specific surface area and better dispersion by~60% less carrier Ln 2O 3 consumption compared with pure Ln 2O 3.
