| Abstract: | Ru/Diatomite catalyst was prepared by impregnation-chemical precipitation method.The properties of the catalyst were investigated by means of BET,EDS.Meanwhile,the hydrogenation performance of hydroquinone over Ru/Diatomite was evaluated.The experimental results showed that the conversion of hydroquinone reached 89.7%and the selectivity of 1,4-cyclohexanediol was 72.0%under the following conditions:0.5g Ru/Diatomite catalyst,3.2MPa reaction pressure,150oC reaction temperature and 5.0h reaction time.The main byproducts were cyclohexanol and 4-hydroxycyclohexanone. |
