Abstract:A series of nickelphyllosilicate derived Ni-PS-AEH-x (different calcination temperatures, the same below) catalysts with a loading of 10% (mass fraction of ruthenium in a catalyst, the same below) nickel were prepared by ammonia evaporation hydrothermal method using nickel nitrate and silica sol as raw material. Ni-PS-AEH-400 was found to have the best catalytic performance by investigating the hydrogenation performance of different nickel-based catalysts. By investigating the influence of reaction conditions, the optimal reaction conditions were as follows: molar ratio of quinoline : Ni is 30 : 1, reaction temperature was 100 ℃, hydrogen pressure was 3 MPa, reaction time was 120 min, and the quinoline conversion rate was 99.0%, the yield of 1,2,3,4-tetrahydroquinoline was 95.4%.The structure, composition and morphol-ogy of catalysts were characterized by XRD, TEM, N2 adsorption-desorption, H2-TPR, and XPS. The re-sults indicated that Ni-PS-AEH-400 exhibited better catalytic performance, attributed to larger specific surface area, active particle higher dispersion and stronger interaction between the active particles and the support compared with Ni/SiO2-IMP prepared by impregnation method.
