     the mgf2–mgo system of different quantitative compositions was tested as a potential support for nickel catalysts to be used for hydrogenation of toluene. the catalytic performance of the system was studied as a function of the mgf2/mgo ratio in the support and the reaction conditions. the hydrogenation was performed at temperatures ranging from 75 to 225 °c on the catalysts activated in hydrogen at different temperatures (400–550 °c). the activities of ni/mgf2–mgo catalysts were compared to those of ni/mgf2, ni/mgo and ni/al2o3. the highest activities were observed in the case of the catalysts supported on mgf2–mgo (containing 40 mol.% mgo), especially after the activation at 500 °c. the catalytic activity of nickel supported on magnesium oxo-fluoride tested in toluene hydrogenation was much higher than that of ni supported on the commonly used supports such as al2o3 or mgo.
