摘要
以功能高分子模板法制备了活性组分高分散和高选择性的碳二加氢催化剂,通过SEM、TGA和XPS表征表明,催化剂载体表面结构均匀,Pd和Ag的电子相互作用明显,H_2-O_2滴定其分散度达到46.6%。侧线评价转化率和选择性均高于传统方法制备的催化剂,选择性超过70%。
The novel C2 hydrogenation catalysts with high dispersed active component and selectivity were prepared by the method of Functional polymer template and characterized by SEM, TGA and XPS. The results showed that the carrier had uniform surface structure and there was the strong electron interaction between Pd and Ag. The dispersion determined by H2-O2 titration method reached 46.6%. The side-line evaluation results indicated that the conversion and selectivity over the novel catalyst were higher than that over traditional catalyst and the selectivity were over 70%.
