不同元素对Fe/AlPO_4-5催化剂CO加氢反应性能的影响(英文)

本文考察了稀土氧化物，合金和氧化锆对ＡｌＰＯ４５载体和Ｆｅ／ＡｌＰＯ４５催化剂的影响。结果表明，Ｌａ、Ｃｅ和Ｙ稀士氧化物的引入可有效地促进硝酸铁丙酮溶液中制备的Ｆｅ／ＡｌＰＯ４５催化剂在ＣＯ加氢反应中的催化活性；负载不同合金的ＡｌＰＯ４５催化剂具有明显不同的催化反应结果；ＺｒＯ可调变ＡｌＰＯ５载体的表面性能，削弱活性组份和载体间的相互作用，使在硝酸铁水溶液中制备的催化剂在合成气转化中具有一定的催化活性。

EFFECTS OF DIFFERENT PROMOTERS ON Fe/AlPO4-5 CATALYSTS IN CO HYDROGENATION

The influences of rare earth oxides, alloy and ZrO 2 on AlPO 4 5 support and Fe/AlPO 4 5 catalyst were investigated. The results showed that the introduction of La, Ce or Y rare earth oxide to the Fe/AlPO 4 5 prepared in a non aqueous acetone solution of iron nitrate, could effectively promote the reaction activity of Fe/AlPO 4 5 in CO hydrogenation; AlPO 4 5 supported alloy metal catalysts had significantly different catalytic results; ZrO 2 could modify the surface properties of AlPO 4 5, weaken the interaction between active component and AlPO 4 5 support, and make the catalyst prepared in a water solution of iron nitrate exhibit catalytic activity in syngas conversion.
