摘要
考察了稀土元素对催化剂的改性作用。研究表明,稀土元素具有和镍相反的对高沸物成分的抑制作用,稀土元素的加入普遍提高了脂肪醇胺化反应的选择性。研究最终确认Gd、Pr、Nd是具有较好改性作用的助催化组分。
The effects of rare earth elements on Reformation of amination-catalyst for fatty alcohol were analyzed in this paper. The results of study showed that rare earth elements mas of opposite-to-Ni restrained effects to high boiling residues, and improved the selectivity of amination-catalyst for fatty alcohol. Gd,Pr and Nd have good effects on reformation of amination-catalyst for fatty alcohol.
