Study on the Ru-Co-B/ZrO_2 catalyst for selective hydrogenation of benzene to cyclohexene;

A Ru-Zn catalyst for selective hydrogenation of benzene to cyclohexene is prepared by co-precipitation of ruthenium trichloride and zinc sulfate with NaOH,followed by hydrogenation reduction in its aqueous mother liquid.

Ru catalysts were prepared by chemical reduction method for selective hydrogenation of benzene to cyclohexene,in which Ru was an active component,Cu and other elements were promoters and ZrO 2 was used as a dispersant.
