Two types of impregnation solvents were suggested for preparation of t
he ruthenium supported catalysts. Charcoal, silica, alumina and titani
a supports were used. Special attention was paid to reduction and acti
vation conditions of nonreduced and passivated forms, respectively. Hy
drogenation of 1-heptene, cyclohexene, benzene and acetophenone in the
liquid phase were studied using the prepared catalysts.
