The effect of supports on catalyst reducibility and hydrogenation activity was investigated. Toluene hydrogenation and hydrogenation of diesel oil fraction to reduce the amt of arom hydrocarbons were carried out in a flow-type pressure reactor. Reactor operating conditions were: < 3-6 MPa, 80-360 °C, LHSV 2-3 h-1, and H2:CH 350-500 Nm3/m3. It was found that the interaction between nickel and TiO2 in the rutile form is considerably stronger than in the case of TiO2 in the anatase form. Deposition of TiO2 on silica surface by TIPOT [Ti-isopropoxide] hydrolysis is an effective method for support preparation; the nickel catalyst may be used for hydrogenation of arom. hydrocarbons.
