Preparation of Lanthanum–Nickel–Aluminium Perovskite Systems and their Application in Methane-Reforming Reactions

In this study we developed LaNixAl1-xO3 perovskite systems using a sol-gelmethod (with propionic acid as solvent) to use in methane-reforming reactions for producing synthesis gas. To understand the roles of the nature of the precursor and calcination conditions on the formation of LaNixAl1-xO3, we carried out identifications using NMR, FT-IR, XRD, SEM, and TEM. The precursor struc...

Hydrogenation of Renewables

Hydrogenation reactions have a variety of applications in the chemical industry which is shown by the corresponding products, such as ammonia, methanol, and polyamides. In petrochemistry, the addition of hydrogen is used to adjust properties of product mixtures, e.g. in the hydrocracking or hydrotreating. For renewables the same is already feasible or first proofs of concept were already shown....

Effect of support nature on performance and kinetics of nickel nanoparticles in toluene hydrogenation

The kinetics of toluene hydrogenation over Ni-supported catalysts with various supports was investigated under the wide range of conditions as 130 to 210 °C reaction temperature, 2.6×10-5 to 5.9×10-5 atm partial pressure of hydrogen and 1.4×10-9 to 3.7×10-8 atm partial pressure of toluene. For more study, two kinetics models were also selected and studied to describe the kinetics of this proces...

Nickel Hydrogenation Composite Catalysts Modified by Zirconium in Competitive Benzene Hydrogenation: Effect of Modifiers

A co-impregnation method was applied to the Ni/Zr-HMS/HZSM-5 catalyst (with various amounts of zirconium) during the hydrogenation of benzene. The physicochemical properties of the prepared nickel catalyst were characterized using X - ray diffraction, X - ray fluorescence, Fourier transform infrared spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy, temperature-programmed desor...
