中文摘要：

考察了（1．0％、4．0％、6．0％）Ru／ZrO2催化剂的丙酸水相加氢性能．采用N2物理吸附、CO脉冲化学吸附、H2程序升温还原（H2-TPR）、CO和丙酸吸附傅里叶变换红外光谱（FTIR）研究了Ru／ZrO2催化剂的物理化学性质．CO—FTIR表明，Ru负载量增加，催化剂表面Ru粒子的富电子程度增加，更接近金属Ru的本征特性．丙酸n1R表明，丙酸分子在Ru／ZrO2催化剂表面经解离吸附主要形成丙酰基和丙酸盐物种．随Ru含量增加，丙酰基更容易发生脱羰反应，导致C—C键断裂．

英文摘要：

The propanoic acid aqueous phase hydrogenation was investigated over the Ru/ZrO2 catalysts with 1.0% , 4.0% and 6.0% Ru loadings. The physieoehemical properties of catalysts were characterized by N2 physi- sorption, CO pulse chemisorption, temperature programmed reduction of H2, Fourier transform infrared spectra （FTIR） of CO and propanoic acid adsorption. The CO-FTIR exhibited that the Ru sites in abundant electron in- creased, and become close to the intrinsic properties of the metal Ru with the increase of the Ru loading over the Ru/ZrO2 catalyst. The F-FIR of propanoie acid adsorption indicated that the molecular propanoic acid mainly formed the propanoyl and propionate species on the Ru/ZrO2 catalyst surface by dissociation adsorption. However, the pro- panoyl species were more readily to rupture the C--C bond by decarbonylation on the Ru sites with the increase of Ru loading.
