摘要

1,4-Cyclohexanedimethanol (CHDM) 是一种高价值的聚酯单体。在 RuSn 和 Pd 催化剂的基础上，通过在 Pd 基催化剂中添加添加剂 Ce，制备了 RuSn 和 PdCe 复合催化剂。结果表明，添加 Ce 后，CHDM 的产率提高了 13.4%，这表明 Ce 有利于活化 HH 和 CO，从而促进羧基的氢化。此外，Ce 的添加还有效减缓了化合物对活性成分钯的覆盖，延长了催化剂的使用寿命。

Synergistic catalytic performance of RuSn and PdCe composite catalysts for the hydrogenation of Terephthalic acid to 1,4-Cyclohexanedimethanol

1,4-cyclohexanedimethanol (CHDM) is used as a high-value polyester monomer. On the basis of the catalysts of RuSn and Pd, the compound catalysts of RuSn and PdCe are prepared by adding the additive Ce to the Pd-based catalyst. The results showed that the yield of CHDM increased by 13.4% after the addition of Ce, indicating that Ce is conducive to the activation of HH and CO thus promoting the hydrogenation of carboxyl groups. Furthermore, the addition of Ce effectively slows down the coverage of the compound on the active component Pd, prolonging the lifespan of the catalyst.
