Abstract: A series of low-loading ruthenium-based catalysts were prepared by impregnation-chemical
reduction method. The introduction of a small amount of W into the Ru-B binary catalyst system improved
the catalytic performance of the catalyst. The structure, composition and surface morphology of the
catalysts were characterized by XPS, H 2-TPD, XRD, SEM and ICP-OES. It was found that the active metal
particles of the catalyst prepared by inverse addition, W addition, ultrasonic assisted technique, and carrier
NaY coated by PEG were dispersed more evenly and the number of active sites was more. The activity of
the catalyst was tested via hydrogenation of hydroquinone to 1,4-cyclohexanediol. The results showed that
Ru-W-B/NaY-IUP(1500) 0.6 (I means reverse addition, U means ultrasound used in the preparation process,
P means PEG used in the preparation process, 1500 means relative molecular mass of PEG, and 0.6 means
PEG dosage, 0.6 g) exhibited the best hydrogenation performance. The conversion of hydroquinone was
99.7%, the selectivity of 1,4-cyclohexanediol was 92.3%, and the ruthenium loading was only 0.45% (mass
fraction of ruthenium in a catalyst, the same below). In addition, the effect of pH value of the reaction
solution on the hydrogenation of hydroquinone was studied. The results revealed that the pH value of the
reaction solution had a great influence on the reaction. When the reaction solution was alkaline, the reaction
rate was greatly accelerated.
