通过将Fe引入Ni/Al2O3制备了Ni-Fe/Al2O3催化剂。运用X射线衍射、程序升温还原技术对改性前后的催化剂进行表征,考察了催化剂在3-羟基丙醛(HPA)加氢反应中的催化性能。结果表明,加入Fe物种后,NiO的可还原性能显著提高,经还原后金属Ni分散度明显增加,催化剂表现出高的加氢活性。在反应温度60℃,反应压力5 MPa,催化剂用量100 mL,原料进料量2 mL/min条件下,1,3-丙二醇转化率达到98%。 The Ni-Fe / Al2O3 catalyst was prepared by introducing Fe into Ni / Al2O3. The catalysts before and after modification were characterized by X-ray diffraction and temperature-programmed reduction. The catalytic performance of the catalyst in 3-HPA hydrogenation was investigated. The results showed that the reducibility of NiO was significantly increased after addition of Fe species, and the dispersity of Ni was obviously increased after reduction. The catalyst showed high hydrogenation activity. The conversion of 1,3-propanediol reached 98% under the conditions of reaction temperature of 60 ℃, reaction pressure of 5 MPa, catalyst dosage of 100 mL and feed rate of 2 mL / min.
