Liquid-phase catalytic hydrogenation of furfural to industrially important furfuryl alcohol was studied at 30 and 50 °C and 2 to 24 atm hydrogen pressure in the presence of Ru-containing catalysts based on new zeolite-like materials such as nickel-phosphate molecular sieves (VSB-5 and Fe-VSB-5) and zirconium-containing organometallic frameworks (UiO-66(Zr)-R, R = H and NH2), as well as materials based on carbon support Sibunit (for comparison). The yield of furfural was shown to depend on the support nature and to increase in the series: Ru/UiO-66(Zr)-NH2 < Ru/UiO-66(Zr) < Ru/Fe-VSB-5 < Ru/VSB-5. The influence of the hydrogen pressure and temperature on selectivity to furfural alcohol was studied.

Hydrogenation of olefinic substrates in binary and ternary mixtures using 5% Pt on silica gel as the catalyst was studied in normal conditions in the liquid phase with methanol or cyclohexane or in solvent-free systems. The effect of the solvent concentration on the selectivity of hydrogenation of the unsaturated alcohol-olefin binary mixtures was investigated. In ternary systems of unsaturated substrates, the effect of each of the substrates on the selectivity of hydrogenation of the remaining two substances was examined. Another system was found in which a jump change of the hydrogenation selectivity occurred on the vanishing of the fastest reacting substance.

Catalytic Test

We have successfully prepared a novel passivation Ni/HY catalyst by the technologies of macerate-precipitatio.The catalysts are comprised of two contents: HY as carrier, Ni as active component，and we put it into the process of preparating aromatic amines.The nature of the catalysts was discussed based on the characterization results of BET , IR , SEM , XRD , TEM ,TPD , XPS and TPR . The catalytic hydrogenation technology for 2,4-dinitrobenzene in liquid phase can be an attractive and elegant routine for production of 2,4-tolylenediamine. The catalytic activity is evaluated at 2.2 MPa, 90 °C, 750r/min, solvent with reaction materials mass ratio of 60, catalyst with reaction materials mass ratio of 0.1. In the catalytic test, The experimental results over the catalyst showed that 2,4-dinitrobenzene and 2,4-tolylenediamine conversion and selective of 99.88% and 99.16% were obtained respectively.It is found that the catalyst is highly dispersion, stable, and reusable. No obvious deactivation of the catalyst was observed after repeated using twelve times.
